YB1220
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.
