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 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 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.
