ZRB500

Precision 5V micropower voltage reference

Description

The ZRB500 uses a bandgap circuit design to

achieve a precision micropower voltage

reference of 5.0 volts. The device is available in

small outline surface mount packages, ideal for

applications where space saving is important,

as well as packages for through hole

requirements.

The ZRB500 design provides a stable voltage

without an external capacitor and is stable with

capacitive loads. The ZRB500 is recommended

for operation between 50␮A and 15mA and so

is ideally suited to low power and battery

powered applications.

Features

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

• ± 3%, 2% and 1% tolerance

• Battery powered and portable equipment

• Operating current 50␮A to 15mA

• Metering and measurement systems

• Typical TC 15ppm/°C

• Instrumentation

• Transient response, stable in less than 10␮s • Test equipment

• Industrial temperature range

• Data acquisition systems

• Small outline SOT23 and TO92 style • Precision power supplies
