KIA7032AF-RTF from KEC Semicon, in a SOT-89-3. 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	VCC	power_in	Positive supply input, absolute max -0.3 V to +15.0 V; nominal 5 V for characterization. Reset output asserts low when VCC falls below the 3.2 V typ. detection threshold (min 3.05 V, max 3.35 V) with ~50 mV hysteresis.
2	GND	power_in	Ground / VEE reference for the device. On the SOT-89 package this pin is common with the heat-sink tab.
3	OUT	output	Active-low reset output (open-collector NPN). Sinks current to pull low when VCC is below the detection threshold; VOL <= 0.4 V at RL = 200 ohm, IOL >= 20 mA at Tc = 25 C. Requires an external pull-up resistor to VCC; leakage in the off state is <= 0.1 uA at VCC = 15 V.
