PRECISION 3.3 VOLT LOW KNEE CURRENT VOLTAGE REFERENCE
ISSUE 5 - JANUARY 2003 DEVICE DESCRIPTION
The ZRC330 uses a bandgap circuit design to achie ve a precision micropower voltage reference of 3.3 volts. The device is available in a small outline surface mount package, ideal for applications where space saving is important. The ZRC330 design provides a stable voltage without an external capacitor and is stable w i t h 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 an absolute maximum of 25mA, however the rugged design and 20 volt processing allows the reference to withstand transient effects a n d cu r r e n t s up to 200mA. Superior sw itching capability allows the device to reach stable operating conditions in only a few microseconds.
