LD56100 Overview
Key Specifications
Length: 1.6 mm
Width: 1.2 mm
Description
The LD56100 high accuracy voltage regulator provides 1 A of current from an input voltage ranging from 1.8 V to 5.5 V, with a typical dropout voltage of 120 mV. It is available in DFN8 (1.2 x 1.6 mm) package, allowing the maximum space saving.
