PRECISION 2.5 VOLT MICROPOWER VOLTAGE REFERENCE

Description

The ZR4040-2.5 uses a bandgap circuit design to achieve a

precision micropower voltage reference of 2.5 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 ZR4040-2.5 design provides a stable voltage without an

external capacitor and is stable with capacitive loads. The

ZR4040-2.5 is recommended for operation between 60

μA

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.
