Description

The RNP50S-302 model is an IC chip that falls under the category of electronic components. This chip is specifically designed for low noise, low dropout (LDO), linear regulators especially for battery-powered equipment and portable devices. It is a dual-channel LDO product that consists of two independent regulators. It provides a 300mV low dropout at 200mA 3.3V output and offers a good power supply rejection ratio (PSRR) of nearly 50dB at 1K~10KHz frequency. Additionally, it supports different output voltages of a full range from 1.2 to 3.6V (pre-set) and consumes a low supply current of 80uA with both regulators enabled.
