Description

The ZR285 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.

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.

Excellent performance is maintained 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.
