PRECISION 2.5 VOLT MICROPOWER

VOLTAGE REFERENCE

ISSUE 6 – JANUARY 2003

DEVICE DESCRIPTION

The ZR285 uses a bandgap circuit

d e s ig n t o a c hi e v e a p re c i s io n

micropower voltage reference of

2.5 volts. The device is available in a

small outline surface mount package,

ideal for applications where space

s a v i ng i s im po rta n t, a s w el l a s

packages

fo r

t hr o ug h

ho l e

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 a bsolute maximum of 30mA,

however the rugged design and 20 volt

processing allows the reference to

w i th s t a nd t ra n s ie n t e ffe c ts an d

c urren ts up to 2 00mA. Supe rior

switching capability allows the device

to reach stable operating conditions in

only a few microseconds.
