AZ1117CD-3.3TRG1

Diodes Incorporated AZ1117CD 3 3TRG1 · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2

AZ1117CD-3.3TRG1 from Diodes Incorporated AZ1117CD 3 3TRG1, in a TO-252-2. 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 / adjust pin. On the fixed 3.3V (AZ1117C-3.3) version the internal adjust resistor divider is factory-connected, so this pin serves as the device ground reference. Connect directly to the system ground plane.
2 OUTPUT power_out Regulated 3.3V output (3.267V-3.333V typ at TJ=+25°C; 3.235V-3.365V over -20°C to +125°C). Requires a minimum 10µF output capacitor with ESR < 20Ω (low-ESR ceramic is compatible). Current limit is 1.35A typical.
3 INPUT power_in Unregulated input supply pin. Absolute maximum 18V; recommended operating maximum 15V. Requires ≥1.5V headroom above VOUT for regulation; dropout at 0.8A is typically 1.3V (TO252-2). A 10µF input capacitor is recommended for stability and transient response.
