7 Detailed Description
7.1 Overview
The LP38690 and LP38692 devices are designed to meet the requirements of portable, battery-powered digital
systems providing an accurate output voltage with fast start-up. When disabled via a low logic signal at the
enable pin (EN), the power consumption is reduced to virtually zero (LP38692 only). The LP38690 and LP38692
perform well with a single 1-μF input capacitor and a single 1-μF ceramic output capacitor.
