Introduction
With each new generation of computing systems, total power continues to increase while system voltages fall. CPU core voltages and logic supplies below 1.8V are now commonplace. Power supplies must not only regulate low output voltages but they must also operate from low input voltages. A low voltage, low dropout linear regulator is an attractive conversion option for applications where ...
