AZ1117CR-2.5TRG1

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89

AZ1117CR-2.5TRG1 from Diodes Incorporated, in a SOT-89. 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 return for the fixed-output regulator. On the fixed AZ1117C-2.5, the internal ADJ network is tied to this pin (the ADJ/GND pin), setting the 2.5V output reference from the internal bandgap.
2 VOUT power_out Regulated 2.5V output. Requires a minimum 10µF output capacitor with ESR < 20Ω (low-ESR ceramic compatible). Delivers up to ~1A with 1.35A typical current limit.
3 VIN power_in Unregulated input supply. Absolute maximum 18V; recommended operating maximum 15V. Requires a minimum 10µF input capacitor. Dropout voltage is ~1.3V typical at IOUT = 0.8A.
