PRECISION 2.5 VOLT MICROPOWER

VOLTAGE REFERENCE

ISSUE 4 - APRIL 2002

ZRA250

DEVICE DESCRIPTION

FEATURES

The ZRA250 uses a bandgap circuit design

to achieve a precision micropower voltage

reference of 2.5 volts. The device is available

in small outline surface mount packages,

ideal for applications where space saving is

important.

Small outline SOT23, SO8 and TO92

style packages.

•

No stabilising capacitor required

Typical T_C30ppm/°C

•

Typical slope resistance 0.4Ω

± 3%, 2%,1% and 0.5% tolerance

Industrial temperature range

Operating current 50µA to 5mA

The ZRA250designprovidesastablevoltage

without an external capacitor and is stable

with capacitive loads. The ZRA250 is

recommended for operation between 50µA

and 5mA and so is ideally suited to low

power and battery powered applications.

Transient response, stable in less than

10µs

Optional extended current range

•

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.

APPLICATIONS

Battery powered and portable

equipment.

•

Metering and measurement systems.

•

Instrumentation.

•

Test equipment.

•

Data acquisition systems.

•

Precision power supplies.
