MIC38300
HELDO® 3A High-Efficiency Low Dropout
Regulator
General Description
The MIC38300 is a 3A peak, 2.
2A continuous output current step down converter.
This is the first device in a new generation of HELDO® (High-Efficiency Low Dropout)
regulators that provide the benefits of an LDO in respect to ease of use, fast transient performance, high PSRR, and low noise while offering the efficiency of a switching
regulator.
As output voltages move lower, the output noise and transient response of a switching
regulator become an increasing challenge for designers.
By combining a switcher whose output is slaved to the input of a highperformance LDO, high efficiency is achieved with a clean low no...
