Description
The RKK-4-23+ is a dual-channel LDO product consisting of 2 independent low noise, low dropout (LDO), linear regulators. It is specially designed for battery-powered equipment and portable devices. The regulator achieves a low 300mV dropout at 200mA 3.3V output and has a good PSRR of near 50dB at 1K~10KHz frequency. The RKK-4-23+ consumes only 80uA supply current with both regulators enabled and supports different output voltages ranging from 1.2V to 3.6V. It is smartly designed to fit in three different pin allocations of SOT23-6 package, providing higher flexibility to users' PCB layout.
