# HLP3985IM5X-3.3

**HXY MOSFET** · Linear Voltage Regulators (LDO) · SOT-23-5L

HLP3985IM5X-3.3 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 supply input, rated for a maximum of 6 V with a typical input of Vout+1 V required for the specified output. |
| 2 | VSS | power_in | Ground reference pin for the regulator. |
| 3 | CE | input | Chip enable input that switches the output off when controlled, reducing shutdown current to 0.1 µA typical (1 µA maximum). |
| 4 | NC | unconnected | No internal connection; leave floating. |
| 5 | VOUT | power_out | Regulated output rated for 300 mA maximum output current across 2.5 V to 3.6 V output range. |
