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 50

µA

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.

FEATURES

• Small outline SO8 and TO92 style

packages

• No stabilising capacitor required

• Typical TC 30ppm/°C

• Typical slope resistance 0.65Ω

• ± 1% tolerance

• Industrial temperature range (Military

temperature range available on request)

• Operating current 50µA to 5mA

• Transient response, stable in less than

10

µs

• Alternative package options and

tolerances available

APPLICATIONS

• Battery powered and portable

equipment.

• Metering and measurement systems.

• Instrumentation.

• Precision power supplies.

• Test equipment.

• Data acquisition systems
