ZLDO330 - 3.3 VOLT ULTRA LOW DROPOUT REGULATOR

General Description

The ZLDO Series low dropout linear regulators operate with an exceptionally low dropout voltage, typically only 30mV with a load current of 100mA.

Key Features

  • output voltages in the range 2.7 to 18 volts, this device provides an output voltage of 3.3 volts. The ZLDO330 consumes a typical quiescent current of only 560µA 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 pulls low. The device also features an active high disable control. Once disabled the ZLDO quiescent current falls.
