PRECISION 2.5 VOLT LOW KNEE CURRENT VOLTAGE REFERENCE

Description

The ZRC250 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 a package for through hole requirements.

The ZRC250 design provides a stable voltage without an

external capacitor and is stable with capacitive loads. The

ZRC250 is recommended for operation between 20

μA 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.
