HG1118M-15AD 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 | Regulator 1 ground / adjust pin. For fixed-output versions this pin is tied to system ground (0 V). For adjustable versions it is the feedback node connected to the R1/R2 divider that sets VOUT1 = 1.25V x (1 + R1/R2). On the -15AD variant, regulator 1 is fixed 1.5V, so this pin is ground. |
| 2 | VIN1 | power_in | Regulator 1 input supply voltage. Recommended operating input is 12V; absolute maximum 15V. Requires a local input decoupling capacitor (~10 uF typical). VIN1 must be at least VOUT1 + Vdropout (typ. 1.3V at 800mA). |
| 3 | GND/ADJ2 | power_in | Regulator 2 ground / adjust pin. On the -15AD variant, regulator 2 is the adjustable channel: this pin is the feedback node connected to an external R1/R2 divider from VOUT2 to GND, setting VOUT2 = 1.25V x (1 + R1/R2). Iadj is typically 60 uA. |
| 4 | VIN2 | power_in | Regulator 2 input supply voltage. Recommended 12V, absolute max 15V. Independent of VIN1 and can be tied to a different rail. Requires input decoupling (~10 uF). |
| 5 | VOUT2 | power_out | Regulator 2 output (adjustable on -15AD). Delivers up to 1A steady-state, current-limited between 2.1A and 2.5A. Requires at least a 22 uF output capacitor on the adjustable version for loop stability. Tie to pin 6 externally. |
| 6 | VOUT2 | power_out | Second bond of regulator 2 output; parallel with pin 5 to share pass-transistor current and improve thermal handling. Connect externally to pin 5. |
| 7 | VOUT1 | power_out | Regulator 1 output (fixed 1.5V on the -15AD variant). Delivers up to 1A steady-state with 2.1-2.5A current limit. Bypass with a suitable output capacitor (fixed version can use smaller than 22 uF). Tie to pin 8 externally. |
| 8 | VOUT1 | power_out | Second bond of regulator 1 output; parallel with pin 7 to share pass-transistor current and improve thermal handling. Connect externally to pin 7. |
