General Description

The ECL5066 is a complex power management, which can provide two roads of low-noise high-speed LDOs and
High efficiency reached 95% of the DC-DC buck.

As the use of CMOS process realization of the work of the chip consumes very little current, the internal use of low-resistance, makes the LDO’s output current of up to 300mA, DC-DC load current of up to 800mA.

A built-in low on-resistance transistor provides a low dropout voltage and large output current, a built-in overcurrent protector prevents the load current from exceeding the current capacitance of the output transistor, and a built-in thermal shutdown circuit prevents damage caused by the heat.Small DFN3×3 package realize high-density mounting.
