# TPS78233DDCT

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

TPS78233DDCT 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; for stable operation place a small 0.1-µF capacitor from this pin to ground, with a typical input capacitor of 1.0 µF. |
| 2 | GND | power_in | Ground pin; tie all ground pins to ground for proper operation. |
| 3 | EN | input | Enable pin; drive above 1.2 V to turn on the regulator and below 0.4 V to put it into shutdown, reducing operating current to 18 nA typical. |
| 4 | GND | power_in | Ground pin; tie all ground pins to ground for proper operation. |
| 5 | OUT | power_out | Regulated output voltage pin; a small (1-µF) ceramic capacitor is needed from this pin to ground to assure stability. |
