SE3335 (Preliminary)
500mA Low Noise CMOS LDO Regulator
General Description
Features
The SE3335 is an efficient linear voltage  Output current up to 500mA
regulator with ultra-low-noise output, very low dropout  Low dropout voltage 600mV(Typ) at 500mA
voltage, and very low ground current. Designed  Low ground current 65uA
specially for battery-powered devices, SE3335  short-current protection
includes an enable/shutdown control function. During  Over-temperature protection
shutdown, power consumption drops nearly to zero.  4 V to 18 V Supply Range
Reversed leakage protection, current limiting, and  Low Shutdown Current
over temperature protection are also included.
 Requires Only 1uF Output Capacitance for
The SE3335 is available in an adjustable version in a
