The LP3998 family are dual input high performance ultra-low dropout （LDO） voltage regulators with high PSRR, fast transient response, and high accuracy. The devices with advanced CMOS process are suitable for many applications that require regulated supplies of up to 500mA load current.
The LP3998 family include standard fixed voltage of 0.8V to 3.6V and adjustable output voltages of 0.8V to 5.0V with an external resister divider. The devices are stable with an effective 1.0μF capacitance ceramic output capacitor. The devices are protected from short circuit by a current limit function and from over-heating by a thermal overload protection.
The devices are available in a DFN1.2x1.2-6 package.
