TP181C33S5-1

TECH PUBLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TP181C33S5-1 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; the datasheet gives an absolute maximum of -0.3 to +20 V and a maximum operating input voltage of 18 V.
2 GND power_in Ground terminal.
3 CE input Chip enable input; VCEH is at least 1.3 V (enabled) and VCEL is at most 0.7 V (disabled), with an absolute maximum of GND-0.3 to VIN+0.3 V.
4 NC unconnected No connection.
5 VOUT power_out Regulated output; the 3.3 V option (TP181C33) has an output of 3.234 to 3.366 V and a maximum output current of 300 mA typical, with an absolute maximum of GND-0.3 to 7 V.
