What is TPS76815QPWPR used for?
TPS76815QPWPR powers processor cores, memory modules, and FPGA I/O banks requiring a regulated 1.5 V supply in automotive infotainment and ADAS systems. The power-good output integrates directly with supervisory circuits to enforce proper power-on sequencing for multi-rail SoC designs. Industrial PLC and communication equipment also use this LDO where tight 1.5 V accuracy and low dropout from a 3.3 V or 5 V intermediate bus are needed.

Frequently Asked Questions
How does TPS76815QPWPR's power-good pin aid multi-rail power sequencing in automotive SoC designs?
The power-good open-drain output asserts high when the 1.5 V output rises above approximately 90 percent of its nominal value. A system supervisor or sequencer IC monitors this signal to delay enabling downstream rails until the processor core supply is stable. This prevents latch-up or undefined logic states in SoCs requiring strict core-before-I/O sequencing, which is critical in automotive ADAS processors operating at -40°C to 125°C.
What is the minimum input voltage TPS76815QPWPR needs to maintain a regulated 1.5 V output at 1 A?
With a 230 mV maximum dropout voltage at 1 A, the minimum input required is 1.73 V to keep the output in regulation. In practice, designers use a 2.7 V minimum input specification for full accuracy, providing over 1 V of headroom above the dropout limit. On a 3.3 V post-buck rail, TPS76815QPWPR delivers the full 1 A at 1.5 V with more than 1.5 V of margin, well within the 10 V maximum input rating.
For a 1 A load on TPS76815QPWPR, how much power does the exposed-pad HTSSOP package need to dissipate?
At 1 A from a 3.3 V input to a 1.5 V output, the dissipated power is approximately 1.8 V times 1 A equaling 1.8 W. The 20-pin HTSSOP exposed thermal pad connects directly to a PCB copper pour, achieving junction-to-board thermal resistance of around 15°C/W, limiting junction temperature rise to 27°C above board temperature. This keeps the device well within its 125°C maximum junction rating at typical 85°C ambient automotive conditions.
Can TPS76815QPWPR replace TPS76715QPWPG4 in an existing board design without layout changes?
Both devices are 1.5 V fixed LDOs in the same 20-pin HTSSOP package with identical pinouts, the same 1 A output, 230 mV dropout, and 2.7 V to 10 V input range. TPS76815QPWPR adds a power-good output pin that TPS76715QPWPG4 does not have, so replacing TPS76715QPWPG4 with TPS76815QPWPR requires only adding a pull-up resistor on the power-good pin and an optional trace to the supervisory circuit. No other PCB changes are needed.
