PRECISION 2.5 VOLT MICROPOWER

VOLTAGE REFERENCE

ZR4040-2.5

ISSUE 4 - JANUARY 2003

DEVICE DESCRIPTION

FEATURES

Small outline SOT23 package

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.

•

TO92 style package

No stabilising capacitor required

Typical T_C30ppm/°C

Typical slope resistance 0.4Ω

2% 1% and 0.5 % tolerance

Industrial temperature range

Operating current 60µA to 15mA

Transient response, stable in less than

10µs

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

low power and battery powered

applications.

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.
