FIXED 2.5 AND 5 VOLT
MINIATURE VOLTAGE REGULATORS
ISSUE 4 - MARCH 2002
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 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.

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.
