TPAP2125K-1.8TRG1 from TECH PUBLIC, 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 | VIN | power_in | Power input pin; input voltage range is 1.8V to 7.0V (absolute maximum 7V). |
| 2 | GND | power_in | Ground pin (shown as Vss in the block diagram). |
| 3 | EN | input | Chip enable pin; CE high voltage is min 1.5V up to VIN, CE low voltage is max 0.3V, and CE=Vss gives standby current of max 0.1µA. |
| 4 | NC | unconnected | No internal connection. |
| 5 | VOUT | power_out | Regulated output pin; the 1.8V version in this MPN has a ±2% output accuracy and 300mA output current, with a 1µF ceramic output capacitor in the typical circuit. |
