SNVS335F – DECEMBER 2006 – REVISED NOVEMBER 2016 LP38853 3-A Fast-Response High-Accuracy Adjustable LDO Linear Regulator
With Enable and Soft Start
1 Features 3 Description The LP38853 is a high-current, fast-response
regulator that can maintain output voltage regulation
with extremely low input-to-output voltage drop.
Fabricated on a CMOS process, the device operates
from two input voltages: VBIAS provides voltage to
drive the gate of the NMOS power transistor; VIN is
the input voltage which supplies power to the load.
The use of an external bias rail allows the device to
operate from ultra-low VIN voltages. Unlike bipolar
regulators, the CMOS architecture consumes
extremely low quiescent current at any output load
current. The use of an NMOS power transistor results
in wide bandwidth, yet minimum external capacitance
is required to maintain loop stability. 1 Wide VBIAS Supply Operating Range: 3 V to 5.5 V
Adjustable VOUT Range: 0.8 V to 1.8 V …
