HMIC5219-3.3YM5

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

HMIC5219-3.3YM5 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 Input supply pin for the regulator, specified for 3.0 V to 15 V operation with an absolute maximum rating of -0.3 V to +20 V.
2 GND power_in Ground reference pin for the device.
3 CE input ON/OFF enable control: a high level of 1.7 V to 15 V enables the output, and a low level of 0 V to 0.3 V puts the device into sleep mode with a standby current of 1.0 µA max.
4 NC unconnected No internal connection; leave this pin unconnected.
5 VOUT power_out Regulated output pin, with an output voltage range of 3.0 V to 5.0 V and an output current of up to 400 mA when VIN = VOUT + 2.0 V.
