PRECISION 2.5 VOLT MICROPOWER
VOLTAGE REFERENCE
ISSUE 5 – FEBRUARY 1998
DEVICE DESCRIPTION
The ZR285 uses a bandgap circuit
de si g n t o a c h i e v e a p r e c i s i on
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, as well as packages for
through hole requirements.
The ZR285 design provides a stable
voltage without an external capacitor
and is stable with capacitive loads. The
ZR285 is recommended for operation
between 20 A and 20mA and so is
ideally suited to low power and battery
powered applications.
Excellent performance is maintained to
an absolute maximum of 30mA,
however the rugged design and 20 volt
processing allows the reference to
wi t hst an d transi ent effects and
currents up to 200mA. Superior
switching capability allows the device
to reach stable operating conditions in
only a few microseconds.
