# LP2985-50DBVR-HXY

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

LP2985-50DBVR-HXY 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; the datasheet gives an absolute maximum input voltage of 16 V and an electrical-table input range of 1.8 V to 15 V. |
| 2 | VSS | power_in | Ground pin; the output voltage is specified between VOUT and this pin, and the absolute maximum VOUT range is VSS-0.3 V to VIN+0.3 V. |
| 3 | CE | input | Enable pin; a high level of 0.3VIN to VIN turns the output on, a low level of 0 to 0.5 V turns it off, and the input current is at most 1 µA. |
| 4 | NC | unconnected | No-connect pin, left floating (悬空) and not used for electrical connection. |
| 5 | VOUT | power_out | Regulated output pin, rated for up to 150 mA maximum output current per the feature list, with an absolute maximum output current of 200 mA. |
