资料介绍

The MST54XXB series is a high input voltage (45V), low quiescent current (2.1uA), low-dropout linear regulator (LDO) able to provide 300mA load current. The MST54XXB family LDO offers EN pin to enable and disable the LDO output, EN pin can take 45V 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.

The device is available with fixed output voltages of 1.8V, 3.0V, 3.3V and 5.0V, and available in SOT23 and SOT89 packages.
