**TECH PUBLIC** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-353

TP142C33C5-1 from TECH PUBLIC, in a SOT-353. 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 | Input of supply voltage, operating from 1.2V to 5.5V (absolute maximum -0.3V to 6.5V to GND). |
| 2 | GND | power_in | Ground. |
| 3 | EN | input | Enable control input (absolute maximum -0.3V to 6V to GND). |
| 4 | NC | unconnected | No internal connection. |
| 5 | VOUT | power_out | Output of the regulator, providing up to 450mA (absolute maximum -0.3V to 6V to GND). |
