PRECISION 5.0 VOLT MICROPOWER VOLTAGE REFERENCE

Description

The ZR4040-5.0 uses a bandgap circuit design to achieve a

precision micropower voltage reference of 5.0 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 ZR4040-5.0 design provides a stable voltage without an

external capacitor and is stable with capacitive loads. The

ZR4040-5.0 is recommended for operation between 60A

and 15mA 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 20ppm/°C

• Typical slope resistance 0.33

• 2% and 1% tolerance

• Automotive temperature range

• Operating current 60A to 15mA

• Transient response,stable in less than 10s

• Green molding compound (No Br, Sb)

Applications

• Battery powered and portable equipment

• Metering and measurement systems

• Instrumentation

• Test equipment

• Data acquisition systems

• Precision power supplies
