HG1118M-3350 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 fixed-output versions (like the -3350) this pin is tied to system ground; in adjustable versions it is the feedback (ADJ) node driven by an external resistor divider referenced to 1.25 V. |
| 2 | VIN1 | power_in | Input supply voltage for regulator 1. Recommended operating input is 12 V and absolute maximum is 15 V. For the 3.3 V output, VIN must be ≥ 4.75 V for the output to remain in regulation over the full 0-1 A load range. |
| 3 | GND/ADJ2 | power_in | Ground / adjust pin for regulator 2. In fixed-output versions (like the -3350, channel 2 = 5.0 V) this pin is tied to system ground; in adjustable versions it is the feedback (ADJ) node driven by an external resistor divider referenced to 1.25 V. |
| 4 | VIN2 | power_in | Input supply voltage for regulator 2. Recommended operating input is 12 V and absolute maximum is 15 V. For the 5.0 V output, VIN must be ≥ 6.5 V for the output to remain in regulation over the full 0-1 A load range. |
| 5 | VOUT2 | power_out | Regulated output of channel 2 (5.0 V ±1.5% for the -3350 variant). Tied internally to pin 6 to share output current up to ~1 A continuous. Requires an output capacitor (≥10 µF typical; ≥22 µF for adjustable versions) for stability. |
| 6 | VOUT2 | power_out | Second bond of regulator 2 output (parallel with pin 5) to reduce package resistance and share the output current. |
| 7 | VOUT1 | power_out | Second bond of regulator 1 output (parallel with pin 8) to reduce package resistance and share the output current. |
| 8 | VOUT1 | power_out | Regulated output of channel 1 (3.3 V ±1.5% for the -3350 variant). Tied internally to pin 7 to share output current up to ~1 A continuous. Requires an output capacitor (≥10 µF typical; ≥22 µF for adjustable versions) for stability. |
