TPS7A0331PDBVR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TPS7A0331PDBVR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN power_in Input supply pin; use 1µF or larger ceramic capacitor from IN to ground to ensure stable operation and achieve good transient response.
2 GND power_in Ground return pin; connect to board ground plane.
3 EN input Enable input pin (high active); drive above VEN(HI)=1.1V to enable or below VEN(LOW)=0.3V to disable; includes internal pull-down resistor (REN(PULLDOWN)=500kΩ typical) that disconnects when EN is externally driven high and device is enabled.
4 NC unconnected No connection pin; not internally connected, may be grounded or left floating.
5 OUT power_out Regulated output pin; requires 0.5µF or larger effective output capacitor from OUT to ground for stability, use 1µF to 22µF ceramic capacitor for good transient response, place as close as possible to device output.
