TP2019-3.3YN5

TECH PUBLIC TP2019 3 3YN5 · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TP2019-3.3YN5 from TECH PUBLIC TP2019 3 3YN5, 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 power input. Operating range 1.6V to 5.5V (absolute max 6V). Bypass with 1uF ceramic capacitor to GND.
2 GND power_in Ground reference for the regulator.
3 CE input Chip Enable input. Drive high to enable the regulator, low (Vce = 0V) to shut down (standby current ~1uA).
4 NC unconnected No connect. Leave floating or tie as convenient for layout.
5 VOUT power_out Regulated voltage output, fixed 3.3V for -3.3YN5 variant. Rated 300mA typical (450mA absolute max). Requires 1uF ceramic output capacitor to GND.
