ZLD0500

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@. 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 ideal for low power and battery powered applications. Battev powered circuits can make particular use of the low batte~ flag and shutdown features.
