PRECISION 2.45 VOLT
VOLTAGE REFERENCE
ISSUE 3 — MARCH 1998
DEVICE DESCRIPTION
The ZRA245 uses a bandgap circuit design
to achieve a precision voltage reference of
2.45 volts. The device is available in small
outline surface mount packages, ideal for
applications where space saving is
important.
The ZRA245 design provides a stable voltage
without an external capacitor and is stable
with capacitive loads. The ZRA245 is
recommended for operation between 2mA
and 120mA.
