ADM803MAKSZ-REEL7 from Analog Devices, in a SC-70-3. 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	GND	power_in	Ground reference for all signals, 0 V.
2	RESET	output	Active-low open-drain reset output that remains low while VCC is below the reset threshold and for 240 ms (typical) after VCC rises above it, and requires an external pull-up resistor; leakage is 1 µA when VCC > VTH and RESET is deasserted.
3	VCC	power_in	Supply voltage being monitored; operating range is 1.2 V to 5.5 V over −40°C to +125°C, with an absolute maximum of −0.3 V to +6 V.
