TPS73633DCQR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-6

TPS73633DCQR from Texas Instruments, in a SOT-223-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN power_in Input power supply; supports 1.7V to 5.5V input voltage range for regulator operation.
2 OUT output Regulated output voltage; delivers up to 400mA output current with stable operation without external capacitors.
3 GND power_in Ground reference for regulator.
4 NR passive Noise reduction pin (fixed voltage version only); connect external capacitor to ground to reduce output noise below 30µVRMS.
5 EN input Enable control pin; drive above 1.7V to enable regulator operation, below 0.5V for shutdown mode.
6 GND power_in Ground reference for regulator.
