HG1118M-50AD

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

HG1118M-50AD 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. Tied to GND for the fixed 5.0V channel on the -50AD variant; on the adjustable channel it becomes the ADJ feedback node sourcing ~60µA (typ) referenced to the 1.25V internal bandgap.
2 VIN1 power_in Regulator 1 supply input. Recommended operating voltage 12V, absolute maximum 15V. For 5.0V fixed output, VIN must be ≥6.5V (VIN-VOUT ≥1.5V typical for full 1A).
3 GND/ADJ2 passive Regulator 2 ground / adjust pin. On the -50AD variant channel 2 is the adjustable regulator; connect a resistor divider from VOUT2 to this pin and to GND to program VOUT2 = 1.25V × (1 + R1/R2) + Iadj × R1.
4 VIN2 power_in Regulator 2 supply input. Recommended operating voltage 12V, absolute maximum 15V. Must be at least (VOUT2 + dropout) with dropout ≤1.3V at 800mA.
5 VOUT2 power_out Regulator 2 (adjustable) output. Rated 1A steady-state, current limit 2.1-2.5A. Requires at least 22µF output capacitor for stability on the adjustable version.
6 VOUT2 power_out Regulator 2 (adjustable) output - second pin internally tied to pin 5 for current handling and thermal spreading.
7 VOUT1 power_out Regulator 1 fixed 5.0V output. Accuracy ±1.5% (4.925-5.075V at 25°C, IOUT=10mA). Rated 1A steady-state, current limit 2.1-2.5A. Recommended output capacitor ≥10µF.
8 VOUT1 power_out Regulator 1 fixed 5.0V output - second pin internally tied to pin 7 for current handling and thermal spreading.
