CAT6221

The 300mA 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 CAT6221 drive loads up to 300mA. By design, the dual LDO provides fast response time during load current and line voltage changes.

Each LDO CAT6221 is optimized for low noise and high crosstalk isolation. With zero shut down current and a low quiescent current of 100A, the dual LDO is ideal for battery-operated devices with supply voltage from 2.3V to 5.5V.

The dual LDO CAT6221 offers 1% initial accuracy and very low dropout voltage, typical 210mV at 300mA. Stable operation is provided with small 1F ceramic output capacitors, reducing required board space and component cost.

Other features include fold-back current limit and thermal protection.

The dual LDO CAT6221 is available in the tiny 6-lead TSOT-23 package with a maximum height of 0.8mm.
