LN1152B182MR-G from NATLINEAR, in a SOT-23-5L. 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	Regulator supply input. Operating range 2.0 V to 7 V (abs max VSS-0.3 to VSS+8 V). Bypass with a ≥1 µF capacitor placed close to the pin.
2	VSS	power_in	Ground / negative supply return. Route with low parasitic resistance.
3	CE	input	Chip-enable (active-high on the 'B' option, with internal pull-down). VCEH ≥ 1.6 V enables the regulator; VCEL ≤ 0.5 V disables it and drops standby current below 1 µA. Abs max VSS-0.3 to VIN+0.3 V.
4	NC	unconnected	No internal connection. Leave floating or tie to a stable net; do not use as a routing via.
5	VOUT	power_out	Regulated output. Factory-set to 1.8 V (±2%) on the -182 option, sourcing up to 500 mA when VIN ≥ VOUT+1 V. Requires a ≥1 µF (tantalum recommended) output capacitor for stability.
