PRECISION 5.0 VOLT MICROPOWER

VOLTAGE REFERENCE

ISSUE 3 - NOVEMBER 2002

ZR4040-5.0

DEVICE DESCRIPTION

The ZR4040-5.0 uses a bandgap circuit

design to achieve a precision micropower

voltage reference of 5.0 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 ZR4040-5.0 design provides a stable

voltage without an external capacitor and

is stable with capacitive loads. The

ZR4040-5.0 is recommended for operation

between 60µA and 15mA and so is ideally

suited to low power and battery powered

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 and currents up to 200mA.

Superior switching capability allows the

device to reach stable operating

conditions in only a few microseconds.
