EC8806 Datasheet, PDF (1/13 Pages) E-CMOS Corporation – Ultra-Low Noise Ultra-Fast 300mA LDO Regulator

Ultra-Low Noise Ultra-Fast 300mA LDO
Regulator
EC8806
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.
