Dual Channel 200mA LDO
Regulator
Description
The YB1220 family is a dual-channel LDO product consisting of 2 independent low noise, low dropout (LDO), linear
regulators especially designed for battery-powered equipment and portable device. The
regulator achieves a low 300 mV dropout at 200mA 3.3V output and good PSRR of near 50dB at 1K~10KHz frequency. The YB1220 consumes only 80uA supply current with both
regulators enabled and supports different output voltages of full range from 1.2 to 3.6V (pre-set). The YB1220 is smartly designed to fit in three different pin allocations of SOT23-6 package which offers higher flexibility to users’ PCB layout. Other features of YB1220 include a thermal shutdown circuit and an output short-circuit protection.
