PRECISION 2.5 VOLT LOW KNEE CURRENT

VOLTAGE REFERENCE

ISSUE 4 - JANUARY 2003

DEVICE 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 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

an d cu rrents up to 200mA. Superior

switching capability allows the device to

reach stable operating conditions in only a

few microseconds.
