El LP38856 es un regulador de alta corriente y respuesta rápida que mantiene la regulación de salida con una caída de voltaje de entrada y salida extremadamente baja. Manufactured in a CMOS process, the device operates from two input voltages: V_BIASProvides the internal bias and control circuitry for the power supply, as well as the gate driver for the N-MOS power transistor when V_INThe power supply supplies power to the load. The use of an externally biased railway allows partial operation in ultra_INLow voltage V. Unlike bipolar regulators, the CMOS architecture dissipates very low quiescent current at any output load. With an N-MOS power wide bandwidth but minimal external capacitance, transistors are used to maintain loop stability.

The device's fast transient response allows it to be used after powering the DSP, the core voltage of the microcontroller, and the switching power supply regulator. El LP38856 está disponible en paquetes TO-220 y TO-263 de 5 pines.
