Description

The RCILF0399TAZZ is a dual-channel LDO product consisting of 2 independent low noise, low dropout (LDO), linear regulators. It is designed specifically for battery-powered equipment and portable devices. The regulator has a low 300mV dropout at 200mA 3.3V output and a good power supply rejection ratio (PSRR) of near 50dB at 1K~10KHz frequency. The RCILF0399TAZZ consumes only 80µA supply current with both regulators enabled and supports different output voltages ranging from 1.2V to 3.6V (pre-set). It is available in three different pin allocations of SOT23-6 package, providing higher flexibility in PCB layout.
