HGSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · ESOP-8

HG1118M-1515 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 (fixed version) or adjust pin (adjustable version). For the -1515 fixed 1.5V variant this pin serves as the ground return for channel 1.
2 VIN1 power_in Regulator 1 input supply voltage. Recommended operating VIN = 12V, absolute maximum 15V.
3 GND/ADJ2 power_in Regulator 2 ground (fixed version) or adjust pin (adjustable version). For the -1515 fixed 1.5V variant this pin serves as the ground return for channel 2.
4 VIN2 power_in Regulator 2 input supply voltage. Recommended operating VIN = 12V, absolute maximum 15V.
5 VOUT2 power_out Regulator 2 regulated output voltage (1.5V for the -15xx suffix). Tied internally with pin 6 to share output current up to 1A steady state. Requires an output capacitor (>=22uF for adjustable, smaller acceptable for fixed).
6 VOUT2 power_out Regulator 2 regulated output voltage (1.5V for the -15xx suffix). Tied internally with pin 5.
7 VOUT1 power_out Regulator 1 regulated output voltage (1.5V for the -15xx suffix). Tied internally with pin 8 to share output current up to 1A steady state.
8 VOUT1 power_out Regulator 1 regulated output voltage (1.5V for the -15xx suffix). Tied internally with pin 7.
