Description
Zr285-2.5 - Precision 2.5 Volt Micropower Voltage Reference
Manufacturer
Zetex Semiconductors plc.
Datasheet
PRECISION 2.5 VOLT MICROPOWER VOLTAGE REFERENCE
DEVICE 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.
