Safe Operating Area (SOA) & Thermal Characteristics
No official SOA curve available for this component. Always operate within absolute maximum ratings specified in the datasheet. Ensure adequate cooling and derate as needed.
Typical Applications
TPS7A1601QDGNRQ1 is suitable for 6 applications: Automotive 12V/24V Battery Rails, 48V Automotive and Industrial Systems, Always-On MCU Standby Supply, Industrial Sensor and Instrumentation Power, CAN/LIN Network Node Bias Supply, Power-Rail Sequencing in Multi-Rail Systems.
Automotive 12V/24V Battery Rails
The TPS7A1601QDGNRQ1's 4.5V-60V input range with UVLO tolerates automotive 12V and 24V battery systems including load-dump-exposed nodes. Its AEC-Q100 qualification and -40C to +125C operation meet automotive grade requirements directly. Placed between the battery node and sensor/MCU rails, it provides clean regulation downstream of transient suppression; at 24V input powering a 5V rail at 50mA, dissipation is under 1W, manageable with the PowerPAD copper plane. Trade-off: at very high VIN, output current must be thermally derated.
Recommended
48V Automotive and Industrial Systems
For 48V mild-hybrid and industrial power distribution, the 60V maximum input rating of the TPS7A1601QDGNRQ1 provides needed headroom where standard LDOs fail. The 5uA quiescent current suits always-on diagnostic rails in 48V zones. Use it as a local bias/standby regulator feeding gate-driver or controller supply domains, typically after a wide-VIN buck stage. At 48V to 10V conversion, keep continuous load below roughly 20-30mA to stay within thermal limits of the HVSSOP PowerPAD package.
Recommended
Always-On MCU Standby Supply
The TPS7A1601QDGNRQ1 was explicitly designed for microcontroller-based, battery-powered systems: its 5uA IQ minimizes standby drain, the CMOS-compatible EN pin allows system-level power gating, and the open-drain power-good output with programmable delay guarantees safe MCU startup sequencing. In automotive body and gateway ECUs, it powers an always-on MCU domain (e.g., MSPM0-class devices) while the main rails are switched. The PG flag lets the MCU confirm rail validity before executing boot code, preventing corrupted-state operation.
Recommended
Industrial Sensor and Instrumentation Power
Industrial 24V sensor loops benefit from the TPS7A1601QDGNRQ1's wide VIN and 5uA IQ for always-on conditioning circuits feeding precision devices such as the ADS1220 delta-sigma ADC or TMCS1101 current sensor. The linear topology adds no switching noise, preserving measurement accuracy on analog rails. The 100mA capacity comfortably powers sensor front ends plus an MCU. Combine with a buck preregulator (e.g., TPS54202DDCR) when VIN-VOUT differential is large to improve overall system efficiency while retaining clean post-regulation.
Recommended
CAN/LIN Network Node Bias Supply
Automotive network nodes using TCAN1042GVDRQ1 CAN or TLIN821-Q1 LIN transceivers require a stable local supply tolerant of battery transients. The TPS7A1601QDGNRQ1's 60V rating and AEC-Q100 qualification cover these conditions directly, and its power-good output can gate transceiver enable signals to prevent bus faults during brownout. The 100mA output powers the transceiver plus a small MCU with margin. Place 1uF ceramics at IN and OUT close to the pins to maintain stability and transient response.
Recommended
Power-Rail Sequencing in Multi-Rail Systems
The TPS7A1601QDGNRQ1's enable pin and power-good output with user-programmable delay make it a sequencing building block in multi-rail systems: rails power up in order as upstream PG flags drive downstream EN pins. A capacitor on the PG delay pin sets the assertion timing. This pattern appears in TI reference designs for MCU-based automotive ECUs where the 60V LDO powers a supervisor domain that then enables main point-of-load converters. The 5uA IQ keeps sequencing circuitry cost negligible in standby states.

Key Differentiators
- AEC-Q100 automotive qualification with 60V VIN (vs TPS7A1601DGNR)
- Adjustable output adds flexibility over fixed-output siblings (vs TPS7A1633QDGNRQ1)
- Integrated power-good with programmable delay (vs LP2951ACDMR2G)
Design Notes
Power dissipation is the dominant constraint: Pd = (VIN - VOUT) x IOUT. At VIN = 60V and VOUT = 5V, each 10mA of load adds ~0.55W. Solder the exposed PowerPAD to a minimum 2x2 via-fanout ground plane per the TI TPS7A16-Q1 datasheet layout section; without adequate copper, thermal shutdown may trigger at high VIN differentials.
Place a 1uF (or per datasheet recommended value) ceramic input capacitor within 5mm of the IN pin and an output capacitor close to OUT. Connect the FB divider directly to the OUT trace at the capacitor, not at a distant node, to avoid load-regulation error. Keep the PG pull-up resistor on a clean rail.
Do not exceed the 60V absolute maximum input - account for automotive load-dump transients upstream with TVS protection if the node is directly battery-connected. Use 1% tolerance resistors in the FB divider for output accuracy. Do not leave EN floating in noise environments; tie it to IN for always-on operation.
