HLP2985AIM5X-3.3

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

HLP2985AIM5X-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 Positive supply input for the LDO, rated up to 16 V absolute maximum with an operating range of 2.5-16 V per the features list.
2 VSS power_in Ground pin; the datasheet limits VOUT and CE to between Vss-0.3 V and VIN+0.3 V, referenced to this pin.
3 CE input Enable input that shuts the output off to reduce system power; it is high-active with VCEH of 0.3VIN to VIN and VCEL of 0 to 0.5 V, and draws at most 1 µA.
4 NC unconnected No-connect pin, left floating (suspended) and not used in the application circuit.
5 VOUT power_out Regulated 3.3 V output (±2% accuracy) capable of sourcing a minimum of 150 mA, with an absolute maximum output current of 200 mA.
