LD1086DTTR

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

LD1086DTTR from STMicroelectronics, in a 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 ADJ input Adjust/feedback pin that sets the output voltage via an external resistor divider (VO = VREF x (1 + R2/R1)); reference voltage 1.25 V typical, adjust pin current 40-120 uA (typ/max).
2 OUTPUT passive Regulated output voltage pin, guaranteed up to 1.5 A output current; internally connected to the package tab.
3 IN passive Unregulated DC input supply pin, absolute maximum 30 V, with typical dropout of 1.3 V at 1.5 A relative to the output.

  • Symbol: LD1086DTTR
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: DPAK (KiCad packages3D, STEP)
  • 3D model files: ld1086dttr-etched.step / ld1086dttr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ld1086dttr.step / ld1086dttr.glb are the bare package body.
