HG1118M-AD50 from HGSEMI, in a ESOP-8. 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/ADJ1 | passive | Ground / adjust pin for regulator 1. Tie to GND for the fixed-voltage version, or connect to the top of the feedback divider on the adjustable version (Iadj ≈ 60 µA typ). On this -AD50 SKU, channel 1 is the adjustable channel and this pin is the ADJ input. |
| 2 | VIN1 | power_in | Input supply for regulator 1. Recommended VIN = 12 V, absolute max 15 V. Decouple with ≥10 µF close to the pin. |
| 3 | GND/ADJ2 | passive | Ground / adjust pin for regulator 2. Tie to GND for the fixed-voltage version, or connect to the top of the feedback divider on the adjustable version. On this -AD50 SKU, channel 2 is the fixed 5.0 V channel and this pin is GND. |
| 4 | VIN2 | power_in | Input supply for regulator 2. Recommended VIN = 12 V, absolute max 15 V. Decouple with ≥10 µF close to the pin. |
| 5 | VOUT2 | power_out | Regulated output of channel 2 (fixed 5.0 V on -AD50). Bond to pin 6 (same net) and load with ≥10 µF for stability; adjustable version requires ≥22 µF. Rated 1 A continuous, current limit 2.1-2.5 A. |
| 6 | VOUT2 | power_out | Second bond pad of channel 2 output; internally tied to pin 5. Doubled up to reduce package resistance at 1 A load. |
| 7 | VOUT1 | power_out | Regulated output of channel 1 (adjustable on -AD50, VREF = 1.25 V ±1.5 %). Bond to pin 8 (same net) and connect the top of the ADJ feedback divider here; requires ≥22 µF output capacitor. |
| 8 | VOUT1 | power_out | Second bond pad of channel 1 output; internally tied to pin 7. Doubled up to reduce package resistance at 1 A load. |
