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.

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.
