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

TPS7A0333PDBVR from Texas Instruments, in a SOT-23-5. 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 Unregulated input supply, 1.5 V to 6.0 V (abs max 6.5 V). Requires 1 µF or larger ceramic input capacitor placed close to the pin for best transient response and low input impedance.
2 GND power_in Device ground return. Must be connected to the board ground plane; ground current is 200 nA typical at zero load.
3 EN input Active-high enable input (V_EN(HI) ≥ 1.1 V, V_EN(LOW) ≤ 0.3 V; abs max 6.5 V). Features a smart internal pulldown (~500 kΩ when EN is low) that disconnects after startup to preserve the ultra-low 3 nA shutdown current; driving EN low or floating disables the regulator.
4 NC unconnected No internal connection. May be tied to ground or left floating.
5 OUT power_out Regulated 3.3 V output, up to 200 mA (dropout ~270 mV typical at 200 mA, V_OUT = 3.3 V). Requires an effective 0.5 µF minimum (1 µF nominal, 22 µF max) ceramic capacitor to ground for stability; place close to the pin.
