LP3962EP/LP3965EP

1.5A Fast Ultra Low Dropout Linear Regulators

ENHANCED PLASTIC

General Description

•

Extended Temperature Performance of −40˚C to +125˚C

Baseline Control - Single Fab & Assembly Site

Process Change Notification (PCN)

The LP3962EP/LP3965EP series of fast ultra low-dropout

linear regulators operate from a +2.5V to +7.0V input supply.

Wide range of preset output voltage options are available.

These ultra low dropout linear regulators respond very fast to

step changes in load which makes them suitable for low

voltage microprocessor applications. The LP3962EP/

LP3965EP are developed on a CMOS process which allows

low quiescent current operation independent of output load

current. This CMOS process also allows the LP3962EP/

Qualification & Reliability Data

Solder (PbSn) Lead Finish is standard

Enhanced Diminishing Manufacturing Sources (DMS)

Support

LP3965EP to operate under extremely low dropout condi- Features

tions.

n Ultra low dropout voltage

Dropout Voltage: Ultra low dropout voltage; typically 38mV

at 150mA load current and 380mV at 1.5A load current.

n Low ground pin current

n Load regulation of 0.04%

Ground Pin Current: Typically 5mA at 1.5A load current.

n 15µA quiescent current in shutdown mode

n Guaranteed output current of 1.5A DC

n Available in SOT-223,TO-263 and TO-220 packages

n Output voltage accuracy 1.5%

n Error flag indicates output status (LP3962EP)

n Sense option improves better load regulation

(LP3965EP)

Shutdown Mode: Typically 15µA quiescent current when

the shutdown pin is pulled low.

Error Flag: Error flag goes low when the output voltage

drops 10% below nominal value (for LP3962EP).

SENSE: Sense pin improves regulation at remote loads.

(For LP3965EP)

n Extremely low output capacitor requirements

n Overtemperature/overcurrent protection

Precision Output Voltage: Multiple output voltage options

are available ranging from 1.2V to 5.0V and adjustable

(LP3965EP), with a guaranteed accuracy of 1.5% at room

temperature, and 3.0% over all conditions (varying line,

load, and temperature).

Applications

n Microprocessor power supplies

n GTL, GTL+, BTL, and SSTL bus terminators

n Power supplies for DSPs

n SCSI terminator

n Post regulators

n High efficiency linear regulators

n Selected Military Applications

n Selected Avionics Applications
