Nisshinbo Micro Devices Inc. Voltage Regulators - Linear R1114D401D-TR-FE

The R1114D401D-TR-FE is a low noise, CMOS-based linear voltage regulator with a maximum output current of 150mA. It features a fixed output voltage range from 1.5V to 4.0V in 0.1V increments, with an output voltage accuracy of ¬±2.0%. The device operates with a typical supply current of 75OºA and a low dropout voltage of 0.22V at 150mA output. It offers high ripple rejection of 70dB at 1kHz and 60dB at 10kHz, making it suitable for applications requiring stable voltage supply. The regulator includes built-in fold back protection with a current limit of approximately 40mA during short mode. It is designed for high-density mounting in SOT-23-5, SC-82AB, and SON1612-6 packages, facilitating integration into compact electronic devices. Recommended capacitor values for optimal performance are 1OºF for both input and output when the output voltage is below 2.5V, and 1OºF input with 0.47OºF output for higher voltages. This product is ideal for powering portable communication equipment and battery-operated devices.
