85 VOLT ULTRA LOW DROPOUT REGULATOR
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 2.
85 volts.
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 contr...
