5.0 VOLT ULTRA LOW DROPOUT

REGULATOR

ZLDO500

ISSUE 2 - JULY 1997

DEVICE DESCRIPTION

FEATURES

The ZLDO Series low dropout linear

regulators operate with an exceptionally

low dropout voltage, typically only 30mV

with a load current of 100mA. The regulator

series features output voltages in the range

2.7 to 18 volts, this device provides anoutput

voltage of 5.0 volts.

Very low dropout voltage

6mV dropout at 10mA output

30mV dropout at 100mA output

100mV dropout at 300mA output

5.0 volt fixed output

Other voltages available

Low quiescent current

The ZLDO500 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.

1mA quiescent 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 quiescentcurrent andsmall 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.
