2.85 VOLT ULTRA LOW DROPOUT

REGULATOR

ZLDO285

ISSUE 2 - J UNE 1997

DEVICE DESCRIPTION

FEATURES

The ZLDO Series low dropout linear regulators

operate with an exceptionally low dropout

voltage, typically only 30m V with a load

current of 100mA. The regulator series features

output voltages in the range 2.85 to 12 volts, this

device provides an output voltage of 2.85 volts.

Very low dropout voltage

•

6mV dropout at 10mA output

30mV dropout at 100mA output

100mV dropout at 300mA output

2.85 volt fixed output

The ZLDO285 consumes a typical quiescent

current of only 1mA at its maximum rated

output current of 300mA. A battery low flag is

available to indicate potential power fail

situations. If the input voltage falls to within

200mV of the regulated output voltage then the

error output pulls low. The device also features

an active high disable control. Once disabled

the ZLDO quiescent current falls to typically

11µA.

Other voltages available

Low quiescent current

1mA quiescent (typ) at 300mA output

Low battery flag

Shutdown control

Surface mount package

APPLICATIONS

The ZLDO devices are packaged in Zetex SM8

8 pin small outline surface mount package,

ideal for applications where space saving is

important. The device low dropout voltage,

low quiescent current and small size make it

ideal for low power and battery powered

applications. Battery powered circuits can

make particular use of the low battery flag and

shutdown features.
