FIXED 2.5 AND 5 VOLT
MINATURE VOLTAGE REGULATORS
ISSUE 2- OCTOBER 1995
DEVICE DESCRIPTION
The ZMR250 and 500 three terminal fixed
positive voltage regulators feature internel
current limit and will shut down under thermal
overload conditions
making the devices
almost impossible to destroy.
The circuit design offers an exceptionally small
quiescent current, only 30@4 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 was designed with space saving in
mind and so is available in the small outline
SOT23 package. This tiny package is ideal for
applications where space is restricted. The
device is also available in the through hole
T092 package.
