ZMR series Fixed 2.5, 3.3 and 5 volt miniature voltage regulators
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 30A for the 2.5V device, ideal for low power applications. The initial devices in the series regulate to 2.5 or 5V with a drive capability up to 50mA. The device is designed with space saving in mind and is available in the small outline SOT23 package. The ZMR250 has expanded its input voltage range to 22.5V and the ZMR500 has expanded its input voltage range to 25V; equalling that of the ZMR25H and ZMR50H respectively. The ZMR330 provides a 3.3V output over an input range of 5V to 24V.

Absolute maximum ratings
Input voltage: ZMR25H, ZMR250 ZMR330 ZMR50H, ZMR500 Package power dissipation (Tamb=25 C) Output current (IO) Operating temperature Storage temperature 22.5V 24V 25V SOT23 500mW (Note 3) TO92 600mW 100mA -55 to 125C -65 to 150C
Note:
1. The maximum operating input voltage and output current of the device will be governed bythe maximum power dissipation of the selected package. Maximum package power dissipationis specified at 25C and must be linearly derated to zero at Tamb =125C. 2. The following data represents pulse test conditions with junction temperatures as indicated atthe initiation of the test. Continuous operation of the devices with the stated conditions mightexceed the power dissipation limits of the chosen package. 3. Maximum power dissipation for the SOT23 package, is calculated assuming that the device ismounted on a ceramic substrate measuring 15 x 15 x 0.6mm.
