NCP170ASN300T2G

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

NCP170ASN300T2G 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 Power supply input voltage. Operating range 2.2 V to 5.5 V; absolute max 6.0 V. Requires 1 µF ceramic input capacitor.
2 GND power_in Power supply ground reference.
3 EN input Chip enable pin, active HIGH. V_ENH ≥ 1.2 V enables the regulator; V_ENL ≤ 0.4 V places device in standby (I_STB ~0.1 µA). Absolute max −0.3 to 6.0 V. Internal ~10 nA pull-down current.
4 NC unconnected No connect. Leave floating or tie as convenient for routing.
5 OUT power_out Regulated output pin. Provides fixed V_OUT (device-programmed 1.2-3.6 V, 0.1 V steps; the ASN300 orders 3.0 V) at up to 150 mA. Requires 1 µF ceramic output capacitor. Short-circuit current ~225 mA.
