# TPS7A2055PDBVR

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

TPS7A2055PDBVR 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 voltage supply; 0.47 µF minimum input capacitor recommended to minimize input impedance; place capacitor close to IN and GND pins for best transient response. |
| 2 | GND | power_in | Common ground. |
| 3 | EN | input | Enable input; low voltage (< VEN(LOW)) turns regulator off and discharges output to GND; high voltage (> VEN(HI)) enables regulator output; internal 500 kΩ pulldown holds regulator off by default. |
| 4 | N/C | unconnected | No internal electrical connection. |
| 5 | OUT | output | Regulated output voltage; 1 µF to 200 µF capacitor with 100 mΩ maximum ESR required to ground for stability; internal 150 Ω typical pulldown resistor prevents VOUT charge retention in shutdown mode (VEN < VEN(LOW)). |
