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 cantake 45V input? ? voltage.The LDO features very fast response against linevoltage transient and load current transient, andensures no overshoot voltage during
