LD1086DT50TR

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2(DPAK)

LD1086DT50TR from STMicroelectronics, in a TO-252-2(DPAK). 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 Ground/reference pin (labeled ADJ/GND on the diagram); for this fixed 5.0 V output version this pin is tied internally to ground.
2 VOUT output Regulated 5.0 V output pin (typ. 4.9-5.1 V over load/line/temperature per LD1086#50 table); this pin is physically and electrically connected to the DPAK tab.
3 VIN power_in Unregulated DC input supply pin, absolute maximum 30 V, with a guaranteed dropout of 1.3 V typ / 1.5 V max at IO = 1.5 A.
