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. |
