MCP1825T-5002E from Microchip Tech, in a SOT-223-5. 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	SHDN	input	Active-low shutdown control input: logic-high enables the LDO output, and pulling it to logic-low disables the output, drives PWRGD low, and puts the LDO in a shutdown state with typical quiescent current of 0.1 µA.
2	VIN	power_in	Input voltage supply, with an operating input range of 2.1V to 6.0V; a typical input capacitance of 1 µF to 10 µF is recommended, especially when the source is remote or a battery.
3	GND	power_in	Ground connection that should be tied to a quiet circuit ground, carrying only the LDO quiescent current (typically 120 µA).
4	VOUT	power_out	Regulated output voltage of the LDO, which requires a minimum output capacitance of 1.0 µF for stability.
5	PWRGD	output	Open-drain power good output that indicates when the output is within 92% (typical) of its regulated value, with a typical 2% hysteresis and a fixed 110 µs (typical) power-up delay.

CAD (KiCad official)

Symbol: MCP1825T-5002E
Footprint: Package_TO_SOT_SMD:SOT-223-5
3D model: SOT-223-5, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.45 mm nominal SOT height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
3D model files: mcp1825t-5002e-etched.step / mcp1825t-5002e-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mcp1825t-5002e.step / mcp1825t-5002e.glb are the bare package body.
