General

Description

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/

LP3965EP

to

operate

under

extremely

low

dropout

condi-

tions.

Dropout

Voltage:

Ultra

low

dropout

voltage;

typically

38mV

at

150mA

load

current

and

380mV

at

1.5A

load

current.

Ground

Pin

Current:

Typically

5mA

at

1.5A

load

current.

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)

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).
