ZRB500

PRECISION 5.0 VOLT MICROPOWER VOLTAGE REFERENCE ISSUE 1 - OCTOBER 1995 DEVICE DESCRIPTION The ZRB500 uses a bandgap circuit design to achieve a precision micropower voltage reference of 5.0 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 ZRB500 design provides a stable voltage without an external capacitor and is stable with capacitive loads. The ZRB500 is recommended for operation between 50µA and 15mA 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. FEATURES ZRB500 Small outline SOT23,SO8 and TO92 style packages No stabilising capacitor required Typical TC 15ppm/ °C Typical slope resistance 0.33Ω ± 3%, 2% and 1% tolerance Industrial temperature range Operating current 50µA to 15mA Transient response, stable in less than 10µs APPLICATIONS Battery powered and portable equipment.
