General Description

The LTC®4063 is a standalone linear charger for single cell lithium-ion batteries with an adjustable low dropout linear regulator (LDO).

The adjustable LDO regulates an output voltage between 1.2V to 4.2V at up to 100mA load current.

When the input supply (wall adapter or USB supply) is removed, the LDO regulates the output voltage without interruption.
