AZ1117CH-1.2TRG1
Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223
AZ1117CH-1.2TRG1 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 | power_in | Ground reference for the fixed-output versions; on the ADJ version this pin is the adjust pin, with adjust pin current specified at 60 µA typical and 120 µA maximum. |
| 2 | OUTPUT | power_out | Regulated output of the 1.2 V fixed version; the output capacitor ESR must be less than 20 Ω and a minimum of 10 µF output capacitor is required. |
| 3 | INPUT | power_in | Unregulated supply input with an absolute maximum input voltage of 18 V and a recommended maximum of 15 V. |
