PRECISION 2.5 VOLT MICROPOWER

VOLTAGE REFERENCE

ZR285-2.5

ISSUE 5 – FEBRUARY 1998

FEATURES

DEVICE DESCRIPTION

The ZR285 uses a bandgap circuit

Small outline SOT23 and SO8 packages

TO92 style packages

•

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, as well as packages for

through hole requirements.

No stabilising capacitor required

Low knee current, 15µA typical

Typical T_C30ppm/°C

Typical slope resistance 0.4Ω

± 3%, 2% and 1% tolerance

Industrial temperature range

Operating current 20µA to 20mA

The ZR285 design provides a stable

voltage without an external capacitor

and is stable with capacitive loads. The

ZR285 is recommended for operation

between 20µA and 20mA and so is

ideally suited to low power and battery

powered applications.

APPLICATIONS

Excellent performance ismaintained to

an absolute maximum of 30mA,

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.
