PRECISION 2.5 VOLT MICROPOWER

VOLTAGE REFERENCE

ISSUE 5 - JANUARY 2006

DEVICE DESCRIPTION

The ZRA250 uses a bandgap circuit design

to achieve a precision micropower voltage

reference of 2.5 volts. The device is available

in small outline surface mount packages,

ideal for applications where space saving is

important.

The ZRA250 design provides a stable voltage

without an external capacitor and is stable

with capacitive loads. The ZRA250 is

recommended for operation between 50 A

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.
