HG1118M-3333 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. In the fixed-voltage version (as with -3333) this pin is tied to GND; in the adjustable version it becomes the ADJ feedback node (Iadj ~60µA, VREF = 1.25V). |
| 2 | VIN1 | power_in | Input supply for regulator 1. Recommended operating VIN = 12V, absolute max 15V; requires at least (VOUT+1.3V) headroom at 800mA. |
| 3 | GND/ADJ2 | power_in | Ground / adjust pin for regulator 2. In the fixed-voltage version (as with -3333) this pin is tied to GND; in the adjustable version it becomes the ADJ feedback node. |
| 4 | VIN2 | power_in | Input supply for regulator 2. Recommended operating VIN = 12V, absolute max 15V. |
| 5 | VOUT2 | power_out | Regulated output of channel 2 (3.3V for the -3333 variant, 1.5% accuracy, up to 1A). Tied internally in parallel with pin 6 for current sharing; connect a bulk output capacitor (≥10µF typical, ≥22µF for adjustable version). |
| 6 | VOUT2 | power_out | Second pin of channel 2's regulated output; internally connected to pin 5. Both pins should be tied together on the PCB. |
| 7 | VOUT1 | power_out | Regulated output of channel 1 (3.3V for the -3333 variant, 1.5% accuracy, up to 1A). Tied internally in parallel with pin 8; connect a bulk output capacitor (≥10µF typical). |
| 8 | VOUT1 | power_out | Second pin of channel 1's regulated output; internally connected to pin 7. Both pins should be tied together on the PCB. |
