SNVS361E – JULY 2007 – REVISED NOVEMBER 2015 LP38513 3-A Fast Response Ultra-Low Dropout Linear Regulator
1 Features 3 Description The LP38513 fast-response ultra-low dropout linear
regulator operates from a 2.25-V to 5.5-V input
supply. This device responds very quickly to step
changes in line or load conditions, making it suitable
for
low-voltage
microprocessor
applications.
Developed on a CMOS process, with a PMOS pass
transistor, the LP38513 has low quiescent-current
operation independent of the output load current. Ground Pin Current: Typically 12 mA at 3-A load
current. Disable Mode: Typically 60 ВµA quiescent current
when the enable (EN) pin is pulled low. ERROR Flag: The ERROR flag goes low if VOUT
falls more than typically 15% below the nominal
value. Precision Output Voltage: A specified VOUT …
