Description

ACE5175X is a low dropout, positive linear regulator with very low quiescent current. It can supply

600mA output current with a input range from 1.7V to 7V, which makes it suitable for all kinds of

applications.

ACE5175X uses advanced CMOS technology to achieve very low dropout voltage (300mV @600mA).

Fast structural design achieves 75dB PSRR at 1kHz while still maintaining a small 50uA quiescent current.

Trimming technique is used to guarantee output voltage accuracy within ±1%.

ACE5175X provides full fault protection including current limit, short circuit protection and thermal shut

down.

Only 1uF ceramic capacitor is required to maintain stability and fast response. 4000V HBM ESD is

guaranteed by design.

ACE5175X is available in SOT-23-5 package.
