LN1154B182MR-G

NATLINEAR · Linear Voltage Regulators (LDO) · SOT-23-5L

LN1154B182MR-G from NATLINEAR, in a SOT-23-5L. 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 Input supply pin; operating input range is 2.0 V to 7 V (absolute maximum VSS+8 V), with a 2.2 µF or larger input capacitor required.
2 VSS power_in Ground pin.
3 CE input Active-high enable input with built-in pull-down resistor; minimum high level 1.6 V, maximum low level 0.5 V.
4 NC unconnected No connection pin.
5 VOUT power_out Regulated output pin delivering at least 300 mA (VIN ≥ VOUT+1 V), with a 2.2 µF or larger output capacitor required.
