 PRECISION 1.25 VOLT MICROPOWER VOLTAGE REFERENCE
ISSUE 2 - FEBRUARY 1997 DEVICE DESCRIPTION
The ZRA125 uses a bandgap circuit design to achieve a precision micropower voltage reference of 1.25 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 ZRA125 design provides a stable voltage without an external capacitor and is stable with capacitive loads. The ZRA125 is recommended for operation between 50A and 5mA and so is ideally suited to low power and battery powered applications. Excellent performance is maintained to a suggested absolute maximum of 25mA, 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.
