Description
The ZCC541A/B series is a high input voltage (40V), low-dropout linear regulator (LDO) able to provide 1A load current. The ZCC541A/B family LDO offers EN pin to enable and disable the LDO output, EN pin can take 40V input voltage.
The LDO features very fast response against line voltage transient and load current transient, and ensures no overshoot voltage during the LDO start up and short circuit recovery.
The device features integrated short-circuit and thermal shutdown protection.Fixed voltages of 5 .0 V , 3 .3 V , 3 .0 V a n d 1 .8 V are available on ZCC541BKP with adjustable output voltages to 0.6V on ZCC541AKP.
