NCP114ASN280T1G

onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TSOP-5

NCP114ASN280T1G from onsemi, in a TSOP-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN power_in Input supply pin. Operating input voltage range 1.7 V to 5.5 V (abs max 6 V). A ≥1 µF ceramic (X5R/X7R) capacitor to GND is required close to this pin for stability.
2 GND power_in Power supply ground / reference return.
3 EN input Enable input. VEN > 0.9 V turns the regulator on; VEN < 0.4 V places the device in shutdown and (on 'A' variants) activates the ~100 Ω active output discharge. Has an internal ~300 nA pull-down; tie to IN if always-on operation is desired.
4 N/C unconnected Not internally connected. May be tied to ground to improve thermal dissipation.
5 OUT power_out Regulated output voltage (2.8 V nominal for the 280 option, ±1% typ). Requires a ≥1 µF ceramic (X5R/X7R) capacitor to GND close to the pin for stability; ESR should remain below 2 Ω.
