HXY MOSFET · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L
LP2985A-33DBVR-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 | Power supply input; absolute maximum 16 V, with a 10uF input capacitor recommended. |
| 2 | VSS | power_in | Ground pin of the regulator. |
| 3 | CE | input | Enable input that switches the output off to cut power; high level 0.3VIN to VIN, low level 0 to 0.5 V. |
| 4 | NC | unconnected | No connection; left floating. |
| 5 | VOUT | power_out | Regulated output (3.3V version, ±2.5% max over test conditions), up to 150 mA, with a 10uF output capacitor of ESR below 0.5 ohm. |
