ZMR Series FIXED 2.5, 3.3 AND 5 VOLT MINIATURE VOLTAGE REGULATORS Description Pin Assignments The ZMR series of three terminal fixed positive voltage regulators SOT23 feature internal current limit and will shut down under thermal Package Suffix - F 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 GND devices in the series regulate to 2.5 or 5V with a drive capability up to 3 IN 2 OUT 1 50mA. The device is designed with space saving in mind and is available in (Top View) the small outline SOT23 package. The ZMR250 has expanded its input voltage range to 22.5V and the ZMR500 has expanded its input TO92 voltage range to 25V; equaling that of the ZMR25H and ZMR50H Package Suffix - C respectively. The ZMR330 provides a 3.3V output over an input range of 5V to 24V.

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 25C and must be linearly derated to zero at TAMB = +125C. 5. 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. 6. Maximum power dissipation for the SOT23 package, is calculated assuming that the device is mounted on a ceramic substrate measuring 15x15x0.6mm.
