1 FIXED.5 AND 5 VOLT MINIATURE VOLTAGE REGULATORS ISSUE 4 - MARCH ZMR SERIES DEVICE DESCRIPTION The ZMR series of three terminal fixed positive voltage regulators feature internal current limit and will shut down under thermal overload conditions making the devices difficult to destroy. The circuit design offers an exceptionally low quiescent current, only 3 for the.5 volt device, ideal for low power applications. The initial devices in the series regulate to.5 or 5 volts with a drive capability up to 5mA, however, the flexible design will allow other voltage selections to be made. The device is designed with space saving in mind and is available in the small outline SOT3 package. The device is also available in through hole TO9 package. FEATURES Small outline SOT3 package TO9 package.5v and 5V output.5v maximum input voltage () 5V maximum input voltage (ZMR5H) Output current up to 5mA Very low Quiesent current (3) Unconditionally stable Other output voltages possible Internal short circuit current limit VOLTAGE RANGE ZMR5.5V ZMR5 5.V.5V ZMR5H 5.V SCHEMATIC DIAGRAM Vin Vout Gnd 4-4

The maximum operating input voltage and output current of the device will be governed by the maximum power dissipation of the selected package. Maximum package power dissipation is specified at 5 C and must be linearly derated to zero at T amb =5 C.. The following data represents pulse test conditions with junction temperatures as indicated at the initiation of the test. Continuous operation of the devices with the stated conditions might exceed the power dissipation limits of the chosen package. 3. Maximum power dissipation for the SOT3 package, is calculated assuming that the device is mounted on a ceramic substrate measuring 5 x 5 x.6mm.
