AZ1117H-1.8TRE1

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

AZ1117H-1.8TRE1 from Diodes Incorporated, in a SOT-223. 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 for the fixed 1.8V output variant. On the AZ1117-ADJ this pin is instead the ADJ feedback node; on all fixed-output variants (including -1.8) it is tied internally as the regulator ground return.
2 OUTPUT power_out Regulated 1.8V output, up to 1A. Requires at least a 22uF tantalum (or equivalent) output capacitor for stability and transient response.
3 INPUT power_in Unregulated input supply, up to 15V recommended (20V absolute max). Requires at least a 10uF bypass capacitor. Must be at least VOUT + 1.15V (VDROP at 1A) for regulation.
