FIXED 2.5 AND 5 VOLT MINIATURE VOLTAGE REGULATORS ZMR SERIES ISSUE 4 - MARCH 2002 DEVICE DESCRIPTION FEATURES 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 30µA for the 2.5 volt device, ideal for low power applications. The initial devices in the series regulate to 2.5 or 5 volts with a drive capability up to 50mA, 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 SOT23 package. The device is also available in through hole TO92 package. Small outline SOT23 package TO92 package 2.5V and 5V output 22.5V maximum input voltage (ZMR25H) 25V maximum input voltage (ZMR50H) Output current up to 50mA Very low Quiesent current (30µA) Unconditionally stable Other output voltages possible Internal short circuit current limit VOLTAGE RANGE ZMR250 ZMR500 ZMR25H ZMR50H 2.5V 5.0V 2.5V 5.0V SCHEMATIC DIAGRAM Vin Vout Gnd 4-104 ZMR SERIES ABSOLUTE MAXIMUM RATINGS Input voltage (ZMR25H) (ZMR50H) 22.5V 25V ZMR250 ZMR500 20V 20V Package power dissipation (Tamb=25 °C) SOT23 500mW (Note 3) TO92 600mW Output current (IO) 100mA Operating temperature Storage temperature -55 to 125°C -65 to 150°C Note: 1. 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 25 °C and must be linearly derated to zero at Tamb =125°C. 2. 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 SOT23 package, is calculated assuming that the device is mounted on a ceramic substrate measuring 15 x 15 x 0.6mm.
