PRECISION 2.45 VOLT
VOLTAGE REFERENCE
ISSUE 2 — FEBRUARY 1998
DEVICE DESCRIPTION
The ZR404 uses a bandgap circuit design to
achieve a precision voltage reference of 2.45
volts. The device is available in small outline
s ur f a ce mo u n t p a c k a g e s , i d e a l for
a p pl i c a t i on s whe re s pac e s av i ng i s
important as well as a 2 pin TO92 style
package for through hole requirements.
The ZR404 design provides a stable voltage
without an external capacitor and is stable
wi th capaci tive loads. The ZR404 is
recommended for operation between 2mA
and 120mA.
