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; equaling 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 Quiescent Current (30μA)

 Unconditionally Stable

 Internal Short Circuit Current Limit

 Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)

 Halogen and Antimony Free. “Green” Device (Note 3)

Notes: 4. 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.

5. 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.

6. Maximum power dissipation for the SOT23 package, is calculated assuming that the device is mounted on a ceramic substrate measuring

15x15x0.6mm.
