HLP2985IM5X-3.3

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

HLP2985IM5X-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; operating input range is 2.5-16V per the features, with a 16V absolute maximum.
2 VSS power_in Ground pin of the regulator.
3 CE input Enable pin that switches the output off to cut system power; high level is 0.3VIN to VIN, low level is 0 to 0.5V, and the input current is 1uA max.
4 NC unconnected No connection; the datasheet lists it as floating.
5 VOUT power_out Regulated 3.3V output rated for up to 150mA, with a recommended output capacitor of at least 10uF and ESR below 0.5 ohm.
