The ABLIC Inc. S-1131 series linear voltage regulator, part number S-1131B18UA-N4DTFG, provides a stable 1.8V output with a maximum current capability of 300mA. This positive fixed output regulator features a low quiescent current of 1 µA and a supply current of 65 µA, making it suitable for power-sensitive applications. The device operates from an input voltage range up to 6.5V, with a typical dropout voltage of 0.75V at 100mA. Its SOT-89-3 (TO-243AA) package facilitates surface mounting. The regulator includes an Enable pin for control and over-current protection. With a high Power Supply Rejection Ratio (PSRR) of 70dB at 1kHz, it is well-suited for noise-sensitive applications in consumer electronics and industrial control systems. Operating temperature range is -40°C to 85°C.
