2019-3.3YN5G

HXY MOSFET · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L

2019-3.3YN5G from HXY MOSFET, in a SOT-23-5L. 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 input pin, with an absolute maximum input voltage of 7 V.
2 VSS power_in Ground pin of the regulator.
3 CE input Enable pin; the datasheet recommends an enable voltage of 1.1 V, there is an internal 1 MΩ resistor to GND, and shutdown current is below 1 µA with CE at VSS.
4 NC unconnected No-connect pin, left floating.
5 VOUT power_out Regulated power output of 3.3 V for the 3.3 V variant, delivering up to 300 mA.
