TPS781250200DDCR 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 supply pin; input voltage range 2.2V to 5.5V, typically requires 1.0µF ceramic bypass capacitor to ground. |
| 2 | GND | power_in | Ground pin; recommended to tie input and output capacitor grounds back to IC ground with minimal impedance. |
| 3 | EN | input | Enable pin; voltage greater than 1.2V enables regulator output, voltage less than 0.4V puts regulator into shutdown mode reducing quiescent current to 18nA typical. |
| 4 | VSET | input | Voltage select pin for dual-level output; voltage less than 0.4V selects 2.5V output, voltage greater than 1.2V selects 2.0V output. |
| 5 | OUT | output | Regulated output voltage pin providing 2.5V or 2.0V output selected by VSET pin; output accuracy ±2% over line/load/temperature range, maximum output current 150mA, typically requires 1.0µF ceramic output capacitor. |
