Manufacturer Part Number
zr4040-2.5
Description
Zr4040-2.5 - Precision 2.5 Volt Micropower Voltage Reference
Manufacturer
Zetex Semiconductors plc.
Datasheet
PRECISION 2.5 VOLT MICROPOWER
VOLTAGE REFERENCE
ISSUE 4 - JANUARY 2003
DEVICE DESCRIPTION
The ZR4040-2.5 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 packages for
through hole requirements.
The ZR4040-2.5 design provides a stable
voltage without an external capacitor and is
stable with capacitive loads. The ZR4040-2.5
is recommended for operation between
60µA and 15mA and so is ideally suited to
l o w
applications.
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
an d cu rrents up to 200mA. Superior
switching capability allows the device to
reach stable operating conditions in only a
few microseconds.
