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
30μA 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

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.
