TP5108E23E-33

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

TP5108E23E-33 from TECH PUBLIC, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Supply input. Absolute maximum 7V; typical operation Vin = Vout + 1V. Bypass to GND with a 1uF ceramic capacitor close to the pin.
2 GND power_in Device ground reference. Return path for load current and internal reference.
3 CE input Chip Enable (active-high). Drive above VCE (1.1V typ) to enable the regulator; drive to 0V to place the part in shutdown (<1uA standby current).
4 NC unconnected No connection. Leave floating or tie to a convenient net; not internally bonded to any function.
5 VOUT power_out Regulated 3.3V output (±2% tolerance), up to 500mA typical. Requires a 1uF ceramic output capacitor to GND for stability.
