PRECISION 5.0 VOLT MICROPOWER
VOLTAGE REFERENCE
ZR4040-5.0
ISSUE 3 - NOVEMBER 2002
DEVICE DESCRIPTION
FEATURES
Sm all outline SOT23 package
The ZR4040-5.0 uses a bandgap circuit
design to achieve a precision m icropower
voltage reference of 5.0 volts. The device
is available in a sm all outline surface
m ount pa ckage, idea l for a pplications
where space saving is im portant, as well
a s p a c ka g e s fo r t h r o u g h h o le
requirem ents.

TO92 style package
No stabilising capacitor required
Typical TC 20ppm /°C
Typical slope resistance 0.33Ω
2% and 1% tolerance
Autom otive tem perature range
Operating current 60µA to 15m A
The ZR4040-5.0 design provides a stable
voltage without an external capacitor and
is s ta b le w ith ca p a citive lo a d s . Th e
ZR4040-5.0 is recom m ended for operation
between 60µA and 15m A and so is ideally
suited to low power and battery powered
applications.
Transient response,stable in less than
10µs
APPLICATIONS
Battery powered and portable
equipm ent.
•
Excellent perform ance is m aintained to an
absolute m axim um of 25m A, however the
rugged design and 20 volt processing
allows the reference to withstand transient
e ffe cts a n d cu rre n ts u p to 200m A.
Superior switching capability allows the
d e v ic e t o r e a c h s t a b le o p e r a t in g
conditions in only a few m icroseconds.
