3A Fast Ultra Low Dropout Linear Regulator
LP3853/LP3856 Fast Response Ultra Low Dropout Linear Regulators
General Description

The LP3853/LP3856 seriesof fast ultra low-dropout linear
regulators operate froma +2.5Vto +7.0V input supply. Wide
rangeof preset output voltage options are available. These
ultra low dropout linear regulators respond very quicklyto
step changesin load, which makes them suitablefor low
voltage microprocessor applications. The LP3853/LP3856
are developedona CMOS process which allows low quies-
cent current operation independentof output load current.
This CMOS process also allows the LP3853/LP3856to op-
erate under extremely low dropout conditions.
Dropout Voltage:
Ultra low dropout voltage; typically 39mV 300mA load current and 390mVat3A load current.
Ground Pin Current:
Typically 4mAat3A load current.
Shutdown Mode:
Typically 10nA quiescent current when
the shutdownpinis pulled low.
Error Flag:
Error flag goes low when the output voltage
drops 10% below nominal value.
SENSE:
Sensepin improves regulationat remote loads.
Precision Output Voltage:
Multiple output voltage options
are available ranging from 1.8Vto 5.0V witha guaranteed
accuracyof ±1.5%at room temperature, and ±3.0% overall
conditions (varying line, load, and temperature).
Features
Ultra low dropout voltage Stable with selected ceramic capacitors Low groundpin current Load regulationof 0.08% 10nA quiescent currentin shutdown mode Guaranteed output currentof3A DC Availablein TO-263 and TO-220 packages Output voltage accuracy± 1.5% Error flag indicates output status Sense option improves load regulation Overtemperature/overcurrent protection −40˚Cto +125˚C junction temperature range
Applications
Microprocessor power supplies Stable with ceramic output capacitors GTL, GTL+, BTL, and SSTL bus terminators Power suppliesfor DSPs SCSI terminator Post regulators High efficiency linear regulators Battery chargers Other battery powered applications
