The JC54XXB series is a high input voltage (45V),
low quiescent current (2.1uA), low‐dropout linear
regulator (LDO) able to provide 350mA load
current. The JC54XXB 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.
