5.0 VOLT ULTRA LOW DROPOUT REGULATOR
ISSUE 1- DECEMBER 1995
ZLD0500
The ZLDO Series low dropout linear regulators operate with an exceptionally low dropout voltage, typically only 30mV with a load current of 10OmA. The ragulatorseries features output voltages in the range 3.3 to 18 volts, this device provides an output voltage of 5.0 volts.
The ZLD0500 consumes a typical quiescent current of only 630pA and is rated to supply load currents up to 300mA. A battery low flag is available to indicate potential power fail situations. If the input voltage falls to within 300mV of the regulated output voltage then the error output pul Is low. The device also featu res an active high disable control. Once disabled the ZLDO quiescent current falls to typically Ii@.
