LD1086DT33TR

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

LD1086DT33TR 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 for the fixed-output version (labeled ADJ/GND on the pin diagram); sets the regulator's internal reference so the output is regulated to the fixed 3.3 V value.
2 OUTPUT power_out Regulated 3.3 V output pin capable of delivering up to 1.5 A; this pin is electrically the same net as the package tab.
3 INPUT power_in Unregulated DC input supply pin, with an absolute maximum input voltage of 30 V.
