# TPS7A0233PDBVR

**Texas Instruments** · Power Supply Chip · SOT-23-5

TPS7A0233PDBVR 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 pin; use the recommended value or larger ceramic capacitor from IN to ground for best transient response, placed as close to the device input as possible. |
| 2 | GND | power_in | Ground pin that must be connected to ground on the board. |
| 3 | EN | input | Enable pin; driving it logic high enables the device, while logic low or floating disables it, with an internal pulldown that disconnects once EN is driven high and the device has started up. |
| 4 | NC | unconnected | No connect pin, not internally connected; connect to ground or leave floating. |
| 5 | OUT | power_out | Regulated output pin requiring 0.5 µF or greater effective capacitance to ground for stability, with a 1 µF or larger ceramic capacitor recommended for best transient response. |
