Description

General part information

LP38852 Series

The LP38852-ADJ is a high-current, fast-response regulator which 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: VBIASprovides voltage to drive the gate of the N-MOS power transistor, while VINis the input voltage which supplies power to the load. The use of an external bias rail allows the part to operate from ultralow VINvoltages. Unlike bipolar regulators, the CMOS architecture consumes extremely low quiescent current at any output load current. The use of an N-MOS 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, microcontroller core voltages, and switch-mode power supply post-regulators.

130 mV (typical) at 1.5-A load current.
