No Preview Available ! 3.0 VOLT ULTRA LOW DROPOUT
REGULATOR
ZLDO300
ISSUE 2 - JUNE 1997
DEVICE DESCRIPTION
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 2.85 to 12 volts, this
device provides an output voltage of 3.0 volts.
The ZLDO300 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.
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
www.DataSheeit4dUe.caoml for low power and battery powered
applications. Battery powered circuits can
make particular use of the low battery flag and
shutdown features.
