MSK5101 series high-current low-dropout voltage regulators and its application

1 Overview

Rapid development of integrated voltage regulator in the past more than 10 years, at home and abroad have grown to hundreds of species. How the circuit works, with integrated linear regulator and switch integrated voltage regulator. Circuit structure, integrated single-chip voltage regulator and modular integrated voltage regulator. Min pin connection, there are three-Terminal integrated regulator and multi-type integrated voltage regulator. According to Nikon Coolpix S6100 Battery Charger the manufacturing process, semiconductor integrated hybrid integrated voltage regulators voltage regulator, thin film and thick film hybrid integrated voltage regulator. Integrated linear regulator, is poor in low voltage, high current, relatively rapid development of small volume.

MSK5101 is the United States MSKennedy the company developed a new low dropout linear regulator, high current, low power consumption, it has +3V, +5V, +12V and adjustable output. Output transistor PNP Super tubes manufactured using the technology of single-chip, so the series model of input and output voltage difference is very small. Is the internal structure of MSK5101 block diagram shown in Figure 1.
