DEVICE DESCRIPTION

The ZR25D uses a bandgap circuit design to

achieve a precision micropower voltage

reference of 2.5 volts. The device is available

in a small outline SOT23 surface mount

package, ideal for applications where space

saving is important.

The ZR25D design provides a stable voltage

without an external capacitor and is stable

with cap acitive loa ds. The ZR25D 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 SOT23 package.

• No stabilising capacitor required

• Typical TC 30ppm/°C

• Typical slope resistance 0.4Ω

• ± 3%, 2% and 1% tolerance

• Industrial temperature range

• Operating current 50µA to 5mA

• Transient response, stable in less than

10

µs

• Alternative package options available

APPLICATIONS

• Battery powered and portable

equipment.

• Metering and measurement systems.

• Instrumentation.

• Test equipment.

• Data acquisition systems.

• Precision power supplies.
