PRECISION 1.25 VOLT

MICROPOWER VOLTAGE REFERENCE

ZRA125

ISSUE 2 - FEBRUARY 1997

DEVICE DESCRIPTION

•

Typical T_C30ppm/°C

Typical slope resistance 0.65Ω

The ZRA125 uses a bandgap circuit design to

achieve a precision micropower voltage

reference of 1.25 volts. The device is available

in small outline surface mount packages, ideal

for applications where space saving is

important, aswellaspackagesforthroughhole

requirements.

± 3%,2% and 1% tolerance

Industrial temperature range

Operating current 50µA to 5mA

Transient response, stable in less than 10µs

Optional extended current range

The ZRA125 design provides a stable voltage

without an external capacitor and is stable with

capacitive loads. The ZRA125 is recommended

for operation between 50µA and 5mA and so

is ideally suited to low power and battery

powered applications.

APPLICATIONS

•

Battery powered and portable equipment.

Metering and measurement systems.

Instrumentation.

Excellent performance is maintained to a

suggested absolute maximum of 25mA,

however the rugged design and 20 volt

processing allows the reference to withstand

transient effects and currents up to 200mA.

Superiorswitchingcapabilityallowsthedevice

to reach stable operating conditions in only a

few microseconds.

Data acquisition systems.

Precision power supplies.

Test equipment.

FEATURES

•

Small outline SOT23, SO8 and TO92 style

packages

•

No stabilising capacitor required
