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 30

μA 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; equaling that of the ZMR25H and

ZMR50H respectively.

The ZMR330 provides a 3.3V output over an input

range of 5V to 24V.
