NCP603SNADJT1G

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

NCP603SNADJT1G 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 Vin power_in Positive power supply input. Operating range 1.75 V to 6 V (absolute max 6.5 V). Bypass to GND with a 1.0 uF ceramic capacitor.
2 GND power_in Power supply ground; device substrate. Typical ground current 145 uA (max 180 uA) at Iout = 1 mA to 300 mA.
3 ENABLE input Enable input. Pulling below 0.4 V places the device into low-power standby (disable current 0.01 uA typ). Logic high threshold >= 0.9 V. Tie to Vin if the enable function is not used.
4 ADJ input Output voltage adjust input (Adjustable Version, NCP603SNADJ). Internal reference 1.25 V; set Vout = 1.25 V * (1 + R1/R2). Typical input bias current +/-0.75 uA. On fixed-voltage versions this pin is NC (true no connect; PCB traces allowed).
5 Vout power_out Regulated output voltage. Adjustable from 1.25 V to 5.0 V on the ADJ version. Delivers up to 300 mA; short-circuit current typ 650 mA. Requires a 1.0 uF ceramic output capacitor.
