FIXED 2.5 AND 5 VOLT

MINIATURE VOLTAGE REGULATORS

ISSUE 4 - MARCH 2002

DEVICE 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 2.5

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 is designed with space saving in

mind and is available in the small outline

SOT23 package. The device is also available

in through hole TO92 package.

FEATURES

• Small outline SOT23 package

• TO92 package

• 2.5V and 5V output

• 22.5V maximum input voltage

(ZMR25H)

• 25V maximum input voltage (ZMR50H)

• Output current up to 50mA

• Very low Quiesent current (30µA)

• Unconditionally stable

• Other output voltages possible

• Internal short circuit current limit
