Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2
AZ1117CD-ADJTRG1 from Diodes Incorporated, in a TO-252-2. 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 | Adjust pin: on the ADJ version it sets the output voltage through the external resistor divider, with adjust pin current of 60 µA typ and 120 µA max; the fixed versions tie this pin to GND. |
| 2 | OUTPUT | power_out | Regulated output of the AZ1117C; a minimum 10µF output capacitor is required, with ESR less than 20 Ω. |
| 3 | INPUT | power_in | Unregulated input supply; the absolute maximum input voltage is 18 V and the recommended maximum is 15 V. |
