Overview

The LP38853 is a high-current, fast-response regulator that can maintain output voltage regulation with extremely low input-to-output voltage drop. Fabricated on a CMOS process, the device operates from two input voltages: VBIAS provides voltage to drive the gate of the NMOS power transistor; V_IN is the input voltage which supplies power to the load. The use of an external bias rail allows the device to operate from ultra-low V_IN voltages. Unlike bipolar regulators, the CMOS architecture consumes extremely low quiescent current at any output load current. The use of an NMOS power transistor results in wide bandwidth, yet minimum external capacitance is required to maintain loop stability. The fast transient response of this device makes it suitable for use in powering DSP and microcontroller core voltages, and switch-mode power-supply post regulators. Dropout Voltage: 240 mV (typical) at 3-A load current Low Ground Pin Current: 10 mA (typical) at 3-A load current Soft Start: Programmable soft-start time
