1.5A Fast Ultra Low Dropout Linear Regulator
LP3962/LP3965
1.5A Fast Ultra Low Dropout Linear Regulators
General Description

The LP3962/LP3965 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 fastto step
changesin load which makes them suitablefor low voltage
microprocessor applications. The LP3962/LP3965 are de-
velopedona CMOS process which allows low quiescent
current operation independentof output load current. This
CMOS process also allows the LP3962/LP3965to operate
under extremely low dropout conditions.
Dropout Voltage:
Ultra low dropout voltage; typically 38mV 150mA load current and 380mVat 1.5A load current.
Ground Pin Current:
Typically 5mAat 1.5A load current.
Shutdown Mode:
Typically 15µA quiescent current when
the shutdownpinis pulled low.
Error Flag:
Error flag goes low when the output voltage
drops 10% below nominal value (for LP3962).
SENSE:
Sense pin improves regulationat remote loads.
(For LP3965)
Precision Output Voltage:
Multiple output voltage options
are available ranging from 1.2Vto 5.0V and adjustable
(LP3965), witha guaranteed accuracyof ±1.5%at room
temperature, and ±3.0% overall conditions (varying line,
load, and temperature).
Features
Ultra low dropout voltage Low groundpin current Load regulationof 0.04% 15µA quiescent currentin shutdown mode Guaranteed output currentof 1.5A DC Availablein SOT-223,TO-263 and TO-220 packages Output voltage accuracy± 1.5% Error flag indicates output status (LP3962) Sense option improves better load regulation (LP3965) Extremely low output capacitor requirements Overtemperature/overcurrent protection −40˚Cto +125˚C junction temperature range
Applications
Microprocessor power supplies GTL, GTL+, BTL, and SSTL bus terminators Power suppliesfor DSPs SCSI terminator Post regulators High efficiency linear regulators Battery chargers Other battery powered applications
Typical Application Circuits
