Description

The ZRC330 uses a bandgap circuit design to achieve a

precision micropower voltage reference of 3.3 volts. The

device is available in a small outline surface mount

package, ideal for applications where space saving is

important.

The ZRC330 design provides a stable voltage without an

external capacitor and is stable with capacitive loads. The

ZRC330 is recommended for operation between 20µA 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 stabilizing capacitor required

• Low knee current, 15A typical

• Typical slope resistance 0.6

• ± 3%, ± 2% and 1% tolerance

• Industrial temperature range

• Operating current 20A to 5mA

• 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

• Crystal oscillators
