The ABLIC Inc. S-1131 series linear voltage regulator, part number S-1131B49UA-N5ITFU, is a positive fixed output device designed for efficient power management. This component delivers a stable 4.9V output with a maximum current capability of 300mA. Featuring a low quiescent current of 1 µA and an input current of 65 µA, it is suitable for battery-powered applications. The low dropout voltage, specified at 0.28V at 100mA, minimizes power dissipation.
The S-1131B49UA-N5ITFU includes an enable control pin for power sequencing and overcurrent protection for enhanced reliability. Its high power supply rejection ratio (PSRR) of 70dB at 1kHz ensures clean power delivery. Packaged in a SOT-89-3 (TO-243AA) surface-mount configuration, this regulator is ideal for use in consumer electronics, industrial control systems, and automotive applications where stable voltage is critical. It operates within an ambient temperature range of -40°C to 85°C.
