ZR4040-5.0

PRECISION 5.0 VOLT MICROPOWER VOLTAGE REFERENCE ISSUE 2 - MARCH 1998 ZR4040-5.0 DEVICE DESCRIPTION The ZR4040-5.0 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 ZR4040-5.0 design provides a stable voltage without an external capacitor and is stable with capacitive loads. The ZR4040-5.0 is recommended for operation between 60µA and 15mA 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 and currents up to 200mA. Superior switching capability allows the de v i c e t o r e a c h s t a b l e ope ra ti n g conditions in only a few microseconds. FEATURES Small outline SO8 and SOT23 packages TO92 style package No stabilising capacitor required Typical TC 20ppm/°C Typical slope resistance 0.33Ω 2% and 1% tolerance Industrial temperature range Operating current 60µA to 15mA Transient response,stable in less than 10µs APPLICATIONS Battery powered and portable equipment.
