HG1118M-5033 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 | power_in | Ground / adjust pin for regulator 1. On the fixed-output HG1118M-5033 this pin is the ground return for the 5.0 V regulator (F1/F2 internally shorted, A open). |
| 2 | VIN1 | power_in | Input supply for regulator 1 (5.0 V output). Recommended operating VIN = 12 V; absolute max 15 V. Requires an input bypass capacitor (typ. 10 µF) to ground. |
| 3 | GND/ADJ2 | power_in | Ground / adjust pin for regulator 2. On the fixed-output HG1118M-5033 this pin is the ground return for the 3.3 V regulator (F1/F2 internally shorted, A open). |
| 4 | VIN2 | power_in | Input supply for regulator 2 (3.3 V output). Recommended operating VIN = 12 V; absolute max 15 V. Requires an input bypass capacitor (typ. 10 µF) to ground. |
| 5 | VOUT2 | power_out | Regulated 3.3 V output of regulator 2 (±1.5% accuracy). Pins 5 and 6 are internally connected and should be tied together on the board. Requires an output capacitor (typ. 10 µF) to ground for stability. |
| 6 | VOUT2 | power_out | Regulated 3.3 V output of regulator 2 (second bonded pin). Tie to pin 5 to share load current and reduce lead resistance. |
| 7 | VOUT1 | power_out | Regulated 5.0 V output of regulator 1 (second bonded pin). Tie to pin 8 to share load current and reduce lead resistance. |
| 8 | VOUT1 | power_out | Regulated 5.0 V output of regulator 1 (±1.5% accuracy). Pins 7 and 8 are internally connected and should be tied together on the board. Requires an output capacitor (typ. 10 µF) to ground for stability. |
