Nisshinbo Micro Devices Inc. Voltage Regulators - Linear RP109N231D-TR-FE

The RP109N231D-TR-FE is a low noise, 150mA linear voltage regulator from the RP109x series by Quarktwin Technology Ltd. It features a typical supply current of 50¬µA and a standby mode current of 0.1¬µA, making it suitable for battery-powered applications. The dropout voltage is typically 0.25V at 150mA output current, and it offers a ripple rejection of 75dB at 1kHz. The output voltage accuracy is ¬±1.0%, with a temperature-drift coefficient of ¬±30ppm/¬8C for output voltages of 1.8V and above. This regulator operates within an input voltage range of 1.4V to 5.25V and supports output voltages from 0.8V to 3.6V in 0.1V steps. It includes built-in fold-back protection with a current limit of 40mA during short mode. The RP109N231D-TR-FE is packaged in a SOT-23-5 format and is compatible with ceramic capacitors of 0.1¬µF or more, contributing to the downsizing of handheld devices. It is ideal for applications such as portable communication equipment, cameras, and other battery-operated devices.
