Description

The 300 mA CMOS Dual LDO CAT6221 combines in a single TSOT−23 6−lead package two low dropout regulators (LDO), each with its own enable pin.

The regulator outputs drive loads up to 300 mA. By design, the dual LDO provides fast response time during load current and line voltage changes.
