A Product Line of Diodes Incorporated ZRC500 PRECISION 5.0 VOLT LOW KNEE CURRENT VOLTAGE REFERENCE Description Pin Assignments The ZRC500 uses a bandgap circuit design to achieve a SOT23 Package Suffix F 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 V 3 R well as packages for through hole requirements. The ZRC500 design provides a stable voltage without an 1 external capacitor and is stable with capacitive loads. The ZRC500 is recommended for operation between 25A and 2 GND 5mA and so is ideally suited to low power and battery powered applications. (Top View) Excellent performance is maintained to an absolute Pin 1 floating or connected to pin 2 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.
