AZ1117CH-1.8TRG1

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

AZ1117CH-1.8TRG1 from Diodes Incorporated, in a SOT-223. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 ADJ/GND input Ground / regulator common return. On the fixed-voltage AZ1117C-1.8 the ADJ/GND pin functions as ground (the internal divider ties the reference to this node). Connect directly to system ground.
2 OUTPUT power_out Regulated 1.8V output. Nominal 1.8V ±1% at 25°C (1.782-1.818V), ±2% over -20°C to +125°C (1.764-1.836V). Requires a minimum 10 µF output capacitor with ESR < 20 Ω for stability; internally shorted to the SOT-223 tab (pin 4).
3 INPUT power_in Unregulated input supply. Recommended operating range up to 15V (absolute max 18V). Dropout is typically 1.2V (max 1.3V) at 0.8A on SOT-223. A 10 µF input decoupling capacitor is recommended.
