ZRB500 PRECISION 5V MICROPOWER VOLTAGE REFERENCE Description Pin Assignments
The ZRB500 uses a bandgap circuit design to achieve a precision micropower voltage reference of 5.0 volts. The
SOT23 Package Suffix – F
device is available in small outline surface mount packages, ideal for applications where space saving is important, as 2 GND well as packages for through hole requirements. 1 The ZRB500 design provides a stable voltage without an external capacitor and is stable with capacitive loads. The 3 VR ZRB500 is recommended for operation between 50µA and 15mA and so is ideally suited to low power and battery

powered applications.
Pin 1 floating or connected to pin 2
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 device to reach stable operating conditions in only a few microseconds.
