TPS7A0309PDBVR

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

TPS7A0309PDBVR 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 input Input pin; use recommended value or higher ceramic capacitor between IN and ground for excellent transient response and minimal input impedance; place input capacitor as close as possible to device input.
2 GND power_in Ground pin; connect this pin to board ground.
3 EN input Enable pin; drive to logic high to enable device, logic low or floating to disable; has internal pull-down resistor that disconnects when externally driven high and device has started.
4 NC unconnected No connection pin; not internally connected; ground or leave floating.
5 OUT output Regulated output pin; requires 0.5µF or larger effective capacitor between OUT and ground for stability; use 1µF or larger ceramic for excellent transient response; place output capacitor as close as possible to device output.
