Typical Applications
TLS715B0EJV50XUMA1 is suitable for 6 applications: Automotive ECU Power Supply, Industrial 24V Bus Sensor Supply, Body Control Module Standby Rail, Instrument Cluster Display Supply, Sensor and Actuator Supply in ADAS Modules, Infotainment Standby Power Rail.
Automotive ECU Power Supply
The TLS715B0EJV50XUMA1 fits automotive ECU rails because of its 40 V input tolerance and 200 mV dropout at 150 mA. According to the Infineon OPTIREG linear datasheet, the regulator rides through 12 V load-dump and cold-crank events with the output staying above 4.9 V, while AEC-Q100 grade-1 qualification supports body, chassis, and powertrain ECU designs. The 5 µA typical quiescent current keeps standby drain low for permanent-battery nodes, and the PG-DSO-8 package with exposed pad provides sufficient thermal dissipation for 5 V x 150 mA continuous loads. Placed downstream of a pre-regulator or directly on the battery rail, it post-regulates a clean 5.0 V for microcontroller, CAN transceiver, and sensor analog supplies.
Recommended
Industrial 24V Bus Sensor Supply
The TLS715B0EJV50XUMA1 operates on industrial 24 V bus rails up to 40 V input, making it a clean post-regulator for factory sensor and instrumentation nodes. According to the Infineon datasheet, the 36 µA quiescent current suits battery-backed industrial sensors, while ±2 % output accuracy supplies ADC reference and 5 V logic rails directly. Unlike a switching regulator, it adds no EMI ripple, which matters for analog front-end and 4-20 mA loop transmitter boards.
Recommended
Body Control Module Standby Rail
The TLS715B0EJV50XUMA1's 5 µA typical quiescent current makes it ideal for body control module standby rails that must remain alive when the ignition is off. According to the Infineon datasheet, the part draws less than 80 µA even at full load, preserving vehicle battery life over long parking periods. The fixed 5.0 V output with ±2 % accuracy directly powers wake-up logic and LIN/CAN transceivers.
Recommended
Instrument Cluster Display Supply
The TLS715B0EJV50XUMA1 supplies a clean 5 V rail to automotive instrument cluster displays where EMI cleanliness is critical. According to the Infineon datasheet, the linear topology adds no switching noise, eliminating display artifacts and pixel jitter caused by switcher ripple. The exposed-pad PG-DSO-8 package provides adequate thermal dissipation for cluster modules mounted in confined dashboard enclosures.
Recommended
Sensor and Actuator Supply in ADAS Modules
The TLS715B0EJV50XUMA1 powers individual sensor and actuator sub-circuits inside ADAS modules such as radar, camera, and ultrasonic sensor PCBs. According to the Infineon datasheet, the 150 mA rating covers a single sensor IC plus signal-conditioning circuitry, while the wide 40 V input tolerates shared-bus transients. AEC-Q100 grade-1 qualification supports safety-rated sensor designs.
Recommended
Infotainment Standby Power Rail
The TLS715B0EJV50XUMA1 powers standby rails in automotive infotainment head units where the radio and telematics control unit must stay alive at all times. According to the Infineon OPTIREG linear datasheet, the low 36 µA quiescent current minimizes parasitic battery drain during parked vehicle states. The fixed 5.0 V output with ±2 % accuracy supports Bluetooth and cellular module wake-up rails without further regulation.

Key Differentiators
- Highest output current in the TLS715B0 family (vs TLE42744DV50ATMA1)
- Lower quiescent current than cross-brand equivalent (vs NCV4264-2C50R2G)
- Exposed-pad PG-DSO-8 thermal performance (vs TLS715B0EJ V33)
Design Notes
Place input and output ceramic capacitors as close as possible to the IC pins to minimize parasitic inductance. According to the Infineon OPTIREG linear datasheet, a 1 µF X7R ceramic on the input and a 1 µF X7R on the output are the minimum recommended values; increasing to 2.2 µF improves load-transient response. The exposed thermal pad must be soldered to a ground copper pour of at least 50 mm² to keep theta_JA within the JEDEC JESD51-2,-5,-7 reference envelope.
Estimated: at VIN = 12 V, VOUT = 5.0 V, and 150 mA continuous load, power dissipation is roughly (12 - 5) × 0.150 = 1.05 W. According to the JEDEC JESD51-2,-5,-7 board referenced in the Infineon datasheet, theta_JA is around 50 C/W, yielding a junction-temperature rise of approximately 53 C above ambient. Ensure the ambient temperature plus this rise stays within the -40 C to +125 C AEC-Q100 grade-1 window.
Do not apply input voltages above 40 V; load-dump transients on a 12 V automotive bus can reach 35-40 V and will damage the part without sufficient headroom margin. According to the Infineon datasheet, the regulator does not include reverse-polarity protection, so an external series diode or P-MOSFET is required if reverse-battery protection is mandatory. Avoid placing the regulator downstream of a switching pre-regulator's switching node; the linear regulator's PSRR is adequate but EMI susceptibility rises if VIN is noisy.
