TECH PUBLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
TP181C50S5-1 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 supply input; absolute maximum -0.3 to +20 V, maximum operating input voltage 18 V. |
| 2 | GND | power_in | Ground terminal. |
| 3 | CE | input | Chip enable input; high level at least 1.3 V enables the output, low level at most 0.7 V disables it, and absolute maximum is GND-0.3 to VIN+0.3 V. |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | power_out | Regulated output terminal; 5.0 V for the TP181C50 variant, absolute maximum GND-0.3 to 7 V, with 1 uF output capacitor in the typical application. |
