USE LM4040 ZR4040-2.5 PRECISION 2.5 VOLT MICROPOWER VOLTAGE REFERENCE Description Pin Assignments The DIODES™ ZR4040-2.5 uses a bandgap circuit design to achieve
a precision micropower voltage reference of 2.5 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 ZR4040-2.5 design provides a stable voltage without an external
capacitor and is stable with capacitive loads. The ZR4040-2.5 is
recommended for operation between 60μA and 15mA and so is
ideally suited for 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. Top View
