ZRC250
PRECISION 2.5 VOLT LOW KNEE CURRENT VOLTAGE REFERENCE
Description
Pin Assignments
The ZRC250 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 a package for through hole requirements.
SOT23 Package Suffix - F
The ZRC250 design provides a stable voltage without an
external capacitor and is stable with capacitive loads. The
ZRC250 is recommended for operation between 20μA and
5mA and so is ideally suited to low power and battery
powered applications.

Pin 1 floating or connected to pin 1
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.
