NCP163ASN280T1G

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

NCP163ASN280T1G from onsemi, 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 IN power_in Input voltage supply pin; operating input voltage range is 2.2 V to 5.5 V, and absolute maximum VIN is -0.3 V to 6 V.
2 GND power_in Common ground connection.
3 EN input Chip enable: applying VEN < 0.4 V disables the regulator, and pulling VEN > 1.2 V enables the LDO.
4 NC unconnected Not connected; can be tied to the ground plane.
5 OUT power_out Regulated output voltage; the output should be bypassed with a small 1 µF ceramic capacitor.
