General Description

The EC8806 is a 300mA, low dropout and low noise linear regulator with high ripple rejection ratio and fast turn-on time. It has fixed and adjustable versions with output voltage ranging from 1.5V to 5V.
The EC8806 includes a reference voltage source, an error amplifier, driver transistors and an internal current limiter. The current limiter’s holdback circuit operates as a short protection.
The EC8806 works well with low ESR ceramic capacitors, suitable for portable RF and wireless battery-powered applications with stringent space requirements and demanding performance.
It also offers ultra low noise output and has low quiescent current.
