ADM823YYKSZ-R7 from Analog Devices, in a SC-70-5. 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	RESET	output	Active low, push-pull reset output, asserted whenever VCC is below the reset threshold VTH (also on MR low or watchdog timeout).
2	GND	power_in	Ground.
3	MR	input	Active low manual reset input that generates a reset when forced low for at least 1 µs, with a 52 kΩ internal pull-up.
4	WDI	input	Watchdog input that generates a reset if the pin remains low or high for the watchdog timeout; the timer is cleared by a logic transition or a reset.
5	VCC	power_in	Power supply voltage being monitored (absolute maximum −0.3 V to +6 V).
