TLS710B0EJV50XUMA1 Overview
An LDO (Low-Dropout) linear regulator is a class of linear voltage regulator that maintains a tightly regulated output voltage even when the input voltage approaches the output voltage. Within the power-management hierarchy, LDOs sit under linear regulators, which themselves sit under voltage regulators, which fall under power management ICs (PMICs). LDOs are distinguished from switching regulators by their lack of switching noise, making them the regulator of choice for post-switching-rail filtering and noise-sensitive analog blocks.
Key features include a wide 4.0 V to 40 V operating input range, integrated output current limitation, overtemperature shutdown, and an enable input for power sequencing. The device is AEC-Q100 qualified, reflecting its target deployment in the harsh environment of automotive applications including body control modules, instrument clusters, and sensor supply rails. The exposed pad on the PG-DSO-8 package reduces thermal resistance to roughly 55 C/W on a standard 1-oz 2-layer JEDEC EIA/JESD51 footprint, enabling sustained 100 mA operation without external heatsinking at moderate VIN/VOUT deltas.
Internally, the regulator uses a pass element referenced to a precision bandgap, with internal compensation that does not require an external ESR network. Stability is specified for output capacitors as low as 1 µF (X7R ceramic), simplifying BOM and reducing PCB area. Protection features include reverse-polarity robustness on the input, short-circuit current foldback, and thermal shutdown with hysteresis, all of which are critical for automotive load-dump and jump-start scenarios.
Typical applications include automotive body ECUs, CAN/LIN transceiver supply, sensor power rails (e.g., Hall-effect, pressure), and industrial 24 V systems needing a clean 5 V post-switching rail. The 40 V input rating and ±2% accuracy also make the part attractive for white-goods and HVAC control boards exposed to wide input transients.
When designing in this part, place input and output ceramic capacitors as close to the IC pins as possible, and tie the exposed pad to a copper pour that ties back to GND. Designers should also verify that VIN-VOUT × IOUT remains within the package's SOA, especially in 24 V systems where dropout dissipation can approach 1 W at full load.

Typical Applications
TLS710B0EJV50XUMA1 is suitable for 7 applications: Automotive Body Control Module (BCM) 5 V Rail, Sensor Power Supply (Hall, Pressure, TPMS), Industrial 24 V PLC Logic Supply, Instrument Cluster and Infotainment Auxiliary Supply, Battery-Buffered Always-On ECU Supply, White Goods and HVAC Control Board 5 V Rail, Two-Wheeler and Small-EV ECU Supply.
Automotive Body Control Module (BCM) 5 V Rail
The TLS710B0EJV50XUMA1 delivers a clean 5.0 V rail to body control modules that aggregate door, lighting, and mirror functions. With 100 mA continuous output and 40 V input tolerance, the regulator rides through cold-crank dips and load-dump transients on the 12 V battery bus without upstream pre-regulation. Its ±2% output accuracy keeps relay drivers and CAN transceivers within their logic-threshold windows, while the 40 µA quiescent current preserves battery life in always-on standby. Exposed-pad PG-DSO-8 packaging handles sustained (VIN-VOUT) × IOUT dissipation in 12 V body networks.
Recommended
Sensor Power Supply (Hall, Pressure, TPMS)
The TLS710B0EJV50XUMA1 supplies 5 V at 100 mA to analog sensor front-ends including Hall-effect position sensors, pressure transducers, and tire-pressure monitoring modules. The regulator's ±2% output tolerance preserves ADC full-scale accuracy, while the 200 mV dropout ensures stable output during battery cranking when VIN collapses toward 6 V. The AEC-Q100 qualification supports under-hood and wheel-mounted sensor placements exposed to -40 °C to +125 °C swings, and the integrated overtemperature shutdown plus current limit protect against wiring faults.
Recommended
Industrial 24 V PLC Logic Supply
In industrial PLCs and HVAC controllers, the TLS710B0EJV50XUMA1 post-regulates a 24 V bus down to 5 V for logic ICs, isolated transceivers, and microcontrollers. The 40 V input rating tolerates common-mode transients on 24 V factory wiring, while the 200 mV dropout maintains regulation under partial brown-out conditions. AEC-Q100 robustness translates to extended life in industrial environments with continuous vibration and temperature cycling, and the PG-DSO-8 EP package enables dense PCB layouts in DIN-rail-mounted I/O modules.
Recommended
Instrument Cluster and Infotainment Auxiliary Supply
The TLS710B0EJV50XUMA1 powers auxiliary 5 V rails in instrument clusters and infotainment head units — driving display backlight drivers, segment LCD bias networks, and small microcontroller housekeeping blocks. Its 40 µA quiescent current supports standby clock retention when the cluster is dimmed, while the ±2% regulation prevents flickering of LED indicators during radio-frequency interference. The PG-DSO-8 EP package dissipates sustained loads without external cooling, making it ideal for the confined geometry behind dashboard bezels.
Recommended
Battery-Buffered Always-On ECU Supply
The TLS710B0EJV50XUMA1 provides a permanent 5 V bias rail for key-fob receivers, immobilizers, and remote-start ECUs that must remain alive when the ignition is off. The 40 µA quiescent current contributes minimally to parasitic drain while still feeding low-power CAN transceivers and wake-up logic. With reverse-polarity and load-dump robustness baked in, the regulator tolerates jump-start events and reverse-battery hookups without external protection components, reducing BOM cost in compact ECU modules.
Recommended
White Goods and HVAC Control Board 5 V Rail
The TLS710B0EJV50XUMA1 supplies 5 V to logic on white-goods controllers — washing machines, refrigerators, and HVAC thermostats — where wide input transients on rectified mains-coupled rails can reach 30 V. The 40 V input rating absorbs these events without latch-up, while the ±2% regulation ensures consistent touch-button and display-segment behaviour. AEC-Q100 thermal endurance translates to long product life under continuous compressor and heater cycling, and the exposed-pad PG-DSO-8 footprint supports hand-solder rework on legacy control boards.
Recommended
Two-Wheeler and Small-EV ECU Supply
The TLS710B0EJV50XUMA1 powers 5 V rails in two-wheeler ECUs, e-bike controllers, and small-EV dashboard modules exposed to high vibration and temperature swings. Its 40 V input covers 12 V motorcycle electrical systems with stator-driven load-dump spikes, and the AEC-Q100 qualification reflects the automotive-grade expectations of modern e-mobility applications. The PG-DSO-8 EP package handles continuous dissipation in enclosed under-seat enclosures, while the small footprint leaves room for additional Bluetooth or GPS modules.

Design Notes
At VIN=12 V, VOUT=5 V, and 100 mA load, the TLS710B0EJV50XUMA1 dissipates approximately 0.7 W of power. Estimated: with theta_JA around 55 C/W on a 1-oz 2-layer JEDEC footprint, the junction temperature rises ~38 °C above ambient at 25 °C — leaving ample headroom to the 125 °C TJ limit. For 24 V inputs at full load, dissipation nearly doubles to ~1.9 W; in this case use the exposed pad to a copper pour of at least 100 mm² to keep Tj below 125 °C across the full automotive temperature range.
Place input and output capacitors within 3 mm of the IC pins to minimize parasitic inductance that can destabilize the control loop. Use a 100 nF X7R plus 1 µF X7R combination on the input, and a 1 µF X7R minimum on the output (10 µF recommended for transient response). The exposed thermal pad must be soldered to a continuous copper pour that ties back to GND through multiple thermal vias (recommended 4-6 vias, 0.3 mm drill) for effective heat extraction.
Do not float the EN pin — it must be driven either to IN or to a logic-level signal. Do not exceed the absolute maximum input voltage of 45 V (the 40 V rating is operating, not absolute). Inductive loads on the output must include a flyback diode or be decoupled with sufficient bulk capacitance, as the regulator's current limit does not replace external load protection. Avoid placing output capacitance with ESR outside the stable region — ceramic X7R is preferred over tantalum or low-ESR aluminum polymers.
Keep the GND return path under the IC and the exposed pad connected to a single star-point GND. Avoid routing high-current switching traces near the IN pin or feedback trace (although fixed-output versions do not have an external feedback trace, internal routing can still couple noise). On 4-layer boards, dedicate one full layer as a GND plane and stitch the regulator's exposed pad to it with multiple thermal vias for best thermal and EMI performance.
