TPS78233DDCR from Texas Instruments, in a TSOT-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 | Input supply pin, 2.2 V to 5.5 V. Place a small ~0.1 µF (typical 1.0 µF) ceramic capacitor from this pin to ground close to the IC; tie the input and output capacitor grounds back together with minimal impedance. |
| 2 | GND | power_in | Device ground. Tie all ground pins to a common ground plane for proper operation. |
| 3 | EN | input | Enable pin (CMOS logic-compatible). Drive above 1.2 V to turn the regulator on; drive below 0.4 V to enter shutdown, reducing operating current to ~18 nA typical. EN voltage range 0 V to VIN. |
| 4 | GND | power_in | Device ground. Tie all ground pins to a common ground plane for proper operation. |
| 5 | OUT | power_out | Regulated 3.3-V output pin, up to 150 mA. Requires a small ~1 µF ceramic capacitor to ground for stability. Line/load regulation within ±1-2% over recommended conditions. |
