PRECISION 1.25 VOLT

MICROPOWER VOLTAGE REFERENCE

ISSUE 2 - MARCH 1998

DEVICE DESCRIPTION

The ZREF12 uses a bandgap circuit design to

achieve a precision micropower voltage

reference of 1.24 volts. The device is

available in a small outline surface mount

package, ideal for applications where space

saving is important, as well as packages for

through hole requirements.

The ZREF12 design provides a stable voltage

without an external capacitor and is stable

with capacitive loads. The ZREF12 is

recommended for operation between 50µA

and 5mA and so is ideally suited to low

power and battery powered applications.

Excellent performance is maintained to an

absolute maximum of 25mA, however the

rugged design and 20 volt processing allows

the reference to withstand transient effects

and currents up to 200mA. Superior

switching capability allows the device to

reach stable operating conditions in only a

few microseconds.
