The LP3994 is a high performance low dropout （LDO）voltage regulator with wide input voltage range and low quiescent current (1.5μA typical). The device is suitable for a multitude of applications which require a regulated supply of up to 150mA load current. The device uses an advanced CMOS process and a P-MOSFET to achieve fast start-up, high output voltage accuracy and excellent transient response performance.
The LP3994 comes in standard fixed output voltage 3.3V and 5.0V. The device is stable with a 1.0μF~10μF ceramic output capacitor, The device is protected from short circuit by the current limit function and from overheating by thermal overload protection.
The device is offered in SOT23-3， SOT23-5，SOT89-3 package.
