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

AZ1117IH-5.0TRG1 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 5.0V version (the adjust resistors are integrated); the adjust pin current is specified at 60 µA typ and 120 µA max on the ADJ version. |
| 2 | OUTPUT | power_out | Regulated 5.0V output (4.9 V to 5.1 V over the junction temperature range); a minimum 10 µF output capacitor with ESR below 20 Ω is required. |
| 3 | INPUT | power_in | Unregulated input supply, rated 18 V absolute maximum and 15 V maximum recommended, with VIN at least VOUT + 2 V for the specified electrical characteristics. |
