The LT1947EMSE#PBF is a special purpose voltage regulator designed to enable power supply design engineers to have greater control over their designs. This part is especially useful for designs that require greater efficiencies and power management. The LT1947EMSE#PBF is a current limited, low dropout voltage regulator designed to provide a wide input and output range. It is designed to be used in a variety of applications depending on the user\'s needs.

One of the main features of the LT1947EMSE#PBF is its current-limited, low dropout architecture. This feature allows the device to operate in a wide range of input voltage variations, with minimal additional power dissipation. Current limit in the part is set externally, and is adjustable from 1.2A to 3.3A. The device also has a low quiescent current of 5µA, and a maximum quiescent current of 13µA, making it extremely efficient. The part comes in a PBF package, which is a hermetically sealed package that is optimized for efficient thermal management.

The LT1947EMSE#PBF has an input voltage range of 2.7V to 28V, and an adjustable output voltage of 0.6V to 20V. It also has over-current protection, reverse current protection, and thermal protection. The part is designed to have a low output voltage noise, with a maximum noise of 150uVrms. The LT1947EMSE#PBF also features programmable soft-start, which keeps the current draw under control during startup, and a soft-off feature, which reduces the risk of voltage drops during current shutdown. The part also features over-voltage protection and under-voltage lockout.

The LT1947EMSE#PBF is designed for use in a variety of power management applications. It can be used to provide steady, low noise output voltages for sensitive analog circuits, such as op-amps and ADCs, as well as digital circuits. It can also be used to regulate the input voltage for various power supplies, such as switching supplies, linear supplies, and DC/DC converters. It can even be used to provide power conditioning for challenging power supply designs, such as those with large current ripple, variable input voltage, or high current loads. The LT1947EMSE#PBF is a powerful and efficient voltage regulator, capable of providing regulated output voltages in a wide range of applications.
