SOT23 MICROPOWER 1.225V VOLTAGE REFERENCE

DESCRIPTION

The ZXRE4041 is a bandgap circuit designed to

achieve a precision micropower voltage reference of

1.225 volts. The device is available in the small outline

SOT23 surface mount package which is ideal for

applications where space saving is important.

SOT23 tolerance is available to 0.5% C grade for

precision applications. Excellent performance is

maintained over the 30

tolerance devices

A knee current

A to 12mA operating current

APPLICATIONS CIRCUIT

Low quiescent reference from a 1.5V battery source.

range with a typical temperature coefficient of only

20ppm/°C. The device has been designed to be highly

tolerant of capacitive loads so maintaining excellent

stability.

This device offers a SOT23 pin for pin compatible

alternative to LM4041 voltage references. SO8 and

E-Line (TO92 style) packages can also be made

available.

APPLICATIONS

Battery powered equipment

Precision power supplies

Portable instrumentation

Portable communications devices

Notebook and palmtop computers

Data acquisition systems

A/D and D/A converters

Test equipment
