LN1182FF3318MR-G

NATLINEAR · Linear Voltage Regulators (LDO) · SOT-23-6L

LN1182FF3318MR-G from NATLINEAR, in a SOT-23-6L. 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 VOUT2 power_out Regulator 2 output; for this part (suffix 33 18, M type) set to 1.8V, with 2.2µF or larger output capacitor recommended.
2 GND power_in Ground pin shared by both regulators.
3 EN2 input Enable input for regulator 2, active high without pull-down resistor (type F), high level min 1.3V and low level max 0.25V.
4 EN1 input Enable input for regulator 1, active high without pull-down resistor (type F), high level min 1.3V and low level max 0.25V.
5 VIN power_in Power supply input shared by both regulators, operating range 2.0V to 7V (absolute max VSS+10V).
6 VOUT1 power_out Regulator 1 output; for this part set to 3.3V, with 300mA max output current and 2.2µF or larger output capacitor recommended.
