Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89
AZ1117CR2-3.3TRG1 from Diodes Incorporated, in a SOT-89. 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 | power_in | Ground reference pin for the fixed 3.3V version; in the ADJ version this pin is the adjust input, whose pin current is 60µA typical and 120µA maximum. |
| 2 | INPUT | power_in | Unregulated supply input, with input voltage limited to 15V maximum in recommended operating conditions and 18V absolute maximum. |
| 3 | OUTPUT | power_out | Regulated 3.3V output, specified at 3.267V to 3.333V over 1.5V ≤ VIN-VOUT ≤ 10V, with a current limit of 1.35A typical (1A minimum) and a minimum load current of 1.7mA typical; a minimum 10µF output capacitor is required. |
