DESCRIPTION
The LC2201 is a high-efficiency, DC-to-DC stepdown
switching regulators, capable of delivering up
to 1.5A of output current. The device operates from
an input voltage range of 2.6V to 5.5V and provides
an output voltage from 0.6V to VIN. Working at a
fixed frequency of 2MHz allows the use of small
external components, such as ceramic input and
output caps, as well as small inductors, while still
providing low output ripples. This low noise output
along with its excellent efficiency achieved by the
internal synchronous rectifier, making LC2201 an
ideal replacement for large power consuming linear
regulators. Internal soft-start control circuitry
reduces inrush current. Short-circuit and thermal
shutdown protection improves design reliability.
The LC2201 is available in SOT23-5 package.
