AZ1117IH-1.5TRG1

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

AZ1117IH-1.5TRG1 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-output (1.5V) version. In the fixed-voltage AZ1117I-1.5, the internal adjust resistors are connected so that this pin serves as the device ground return. Must be tied to system ground.
2 OUTPUT power_out Regulated 1.5V output (1.485V-1.515V typ at 25°C, ±1% accuracy). Delivers up to 1A with a typical dropout of 1.2V at 0.8A. Requires a minimum 10µF output capacitor with ESR <20Ω for stability; the SOT-223 tab is electrically connected to this pin.
3 INPUT power_in Unregulated supply input. Recommended operating range up to 15V (absolute max 18V). A 10µF input capacitor is recommended to handle line transients. Input must exceed VOUT + VDROP (≈VOUT + 1.2V at 0.8A) for regulation.
