NCP500SN33T1G

onsemi · Linear Voltage Regulators (LDO) · TSOP-5

NCP500SN33T1G from onsemi, in a TSOP-5. 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 power supply input voltage, rated 0 to 6.0 V with a 1.0 µF input capacitor recommended close to the package.
2 GND power_in Power supply ground.
3 Enable input Pulled to logic low it disables the device into low-power standby (turn-on threshold 0.9 V, turn-off 0.15 V max), and it should be connected to Vin if unused.
4 N/C unconnected No internal connection.
5 Vout power_out Regulated output voltage (3.3 V nominal for this part) requiring a minimum 1.0 µF output capacitor, 150 mA maximum load.
