Dual 200mA CMOS
LDO Voltage Regulator
(Preliminary)
SE5221
Description
SE5221 is a dual-channel low dropout
regulator supplying up to 200mA at each channel.
The output voltages are selectable between
2.8V/3.3V for Channel-1 and 1.3V/1.8V for
Channel-2 with 3% accuracy.
The SE5221 uses internal PMOS transistors
as the pass devices to regulate the output voltages.
The IC consumes 120μA supply current when both
channels are turned on, and is nearly independent
of load currents and dropout conditions. The EN1
and EN2 pins allows for individual channel controls.
When both outputs are shut down simultaneously,
the chip will be turned off and consumes nearly zero
operating current which is suitable for battery-power
devices. Other features include a current limiting,
and over temperature protection.
