Description

The ZR4040-4.1 uses a bandgap circuit design to achieve a precision micropower voltage reference of 4.1 volts. The device is available in a small outline surface mount package, ideal for applications where space saving is important, as well as packages for through hole requirements. The ZR4040-4.1 design provides a stable voltage without an external capacitor and is stable with capacitive loads. The ZR4040-4.1 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 device to reach stable operating conditions in only a few microseconds.
