PRECISION 2.45 VOLT
VOLTAGE REFERENCE
ISSUE 2 — FEBRUARY 1998
DEVICE DESCRIPTION
The ZR458 uses a bandgap circuit design to
achieve a precision voltage reference of 2.45
volts.
The ZR458 design provides a stable voltage
without an external capacitor and is stable
with capacitive loads. The ZR458 is
recommended for operation between 2mA
and 120mA.
ZR458
