TPS7A0321PDBVR

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

TPS7A0321PDBVR 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, accepts 1.5V to 6.0V; place 1µF or larger ceramic capacitor close to pin to minimize input impedance and ensure transient response.
2 GND power_in Ground reference pin; connect to board ground plane and thermal pad area for heat dissipation.
3 EN input Enable input with internal pull-down resistor; device enabled when voltage exceeds 1.1V, disabled below 0.3V or when floating.
4 NC unconnected No connection pin; internally unconnected, may be grounded or left floating.
5 OUT power_out Regulated output pin, 0.8V to 5.0V fixed voltage; connect minimum 1µF ceramic capacitor to ground for stability and transient response, supports up to 200mA output current.
