The LP3997 family are high performance low dropout （ LDO ） voltage regulators with ultra-low quiescent current, 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 300mA load current.
The LP3997 family include standard fixed output voltages of 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, and 3.3V. The devices are stable with a 1.0μF~10μF 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 standard SOT23, DFN-4 (1mmx1mm) and SOT23-5 packages.
