Nisshinbo Micro Devices Inc. Voltage Regulators - Linear R1116D251D-TR-FE

The R1116D251D-TR-FE is a low noise, CMOS-based linear voltage regulator designed to provide a fixed output voltage with high accuracy and low supply current. It supports an input voltage range of 1.8V to 6.0V and offers an output voltage range from 1.5V to 4.0V in 0.1V steps. The typical supply current at no load is 10OºA, with a standby current of only 0.1OºA, making it suitable for battery-powered applications. The device features a low dropout voltage of 0.29V at 150mA output current and provides excellent ripple rejection of 70dB at 1kHz. The output voltage accuracy is ±1.5%, and it includes built-in fold-back protection with a current limit of approximately 40mA during short-circuit conditions. The R1116D251D-TR-FE is packaged in a SON1612-6 format, allowing for high-density mounting on circuit boards. It is recommended for use in portable communication devices, music players, and other battery-operated equipment.
