ZXTR2005Z-13 from Diodes Incorporated, 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	GND	power_in	Power ground. This pin should be tied to the system ground and serves as the 0V reference for VIN and VOUT.
2	VIN	power_in	Input supply. Input voltage can vary from -0.3V to 100V with respect to GND; for regulated VOUT, 10V ≤ VIN ≤ 100V. A 1µF capacitor to GND is recommended. This pin is also the exposed thermal pad (heat-sink tab) on the SOT89 package.
3	VOUT	power_out	Regulated voltage output. Outputs 5V ±10% when 10V ≤ VIN ≤ 100V; when VIN < 10V, VOUT max = VIN − 1.5V. The pin can be pulled high to a maximum of +11V with respect to GND, or +5V with respect to VIN, whichever is lower. Connect a 10µF capacitor to GND and draw a minimum of 10µA from VOUT to maintain regulation.
