General Description
The MIC38150 is a 1.5A continuous output current step
down converter. This is a follow on product in the new
HELDO
family, that provide the benefits of an LDO. They are easy
to use, feature 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 high
performance LDO, high efficiency is achieved with a clean
low noise output. The MIC38150 is designed to provide
less than 5mV of peak-to-peak noise and over 70dB of
PSRR at 1kHz. Furthermore, the architecture of the
MIC38150 is optimized for fast load transients allowing the
output to maintain less than 30mV of output voltage
deviation even during ultra fast load steps. This makes the
MIC38150 an ideal choice for low voltage ASICs and other
digital ICs.
The MIC38150 features a fully integrated switching
regulator and LDO combination, operates with input
voltages from 3.0V to 5.5V input and offers adjustable
output voltages down to 1.0V.
