ZMR250

Fixed 2.5, 3.3 and 5 volt miniature voltage regulators

Zetex => Diodes 

ZMR series

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 30µA 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;

equalling that of the ZMR25H and ZMR50H

respectively.

The ZMR330 provides a 3.3V output over an

input range of 5V to 24V.

Features

• Small outline SOT23 package

• 2.5V, 3.3V and 5V output

• Output current up to 50mA

• Very low quiesent current (30µA)

• Unconditionally stable

• Internal short circuit current limit
