A Product Line of Diodes Incorporated ZR4040-4.1 PRECISION 4.1 VOLT MICROPOWER VOLTAGE REFERENCE Description Pin Assignments 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. SOT23 Package Suffix - F 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. (Top View) 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.
