PRECISION 3.3 VOLT LOW KNEE CURRENT VOLTAGE REFERENCE
ISSUE 2 - FEBRUARY 1997 DEVICE DESCRIPTION
The ZRC330 uses a bandgap circuit design to a chie ve a precision micropower voltage reference of 3.3 volts. The device is available in small outline surface mount packages, ideal f o r applications where space saving is important. The ZRC330 design provides a stable voltage without an external capacitor and is stable with capacitive loads. The ZRC330 is recommended for operation between 20µA and 5mA and so is ideally suited to low power and battery powered applications. Excellent performance is maintained to a sugge ste d 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. FEATURES
