NCP163ASN300T1G

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

NCP163ASN300T1G 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 range 2.2 V to 5.5 V.
2 GND power_in Common ground connection.
3 EN input Chip enable: VEN < 0.4 V disables the regulator and VEN > 1.2 V enables the LDO; internal 200 nA typ pull-down turns the device off if left unconnected.
4 NC unconnected Not connected internally; can be tied to ground plane.
5 OUT power_out Regulated output voltage (3.0 V for this option); the output should be bypassed with a small 1 µF ceramic capacitor.
