TP9001-28S5

TECH PUBLIC · Linear Voltage Regulators (LDO) · SOT-23-5

TP9001-28S5 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 Supply power input; absolute maximum input voltage is 7 V.
2 GND power_in Ground.
3 CE input Enable pin; CE enable voltage is 1.1 V (min) and standby current is 1 uA max at VCE=0V.
4 NC unconnected No connection.
5 VOUT power_out Regulated voltage output (2.8 V for this -28 variant) delivering up to 500 mA.
