1 / 6 page  Issue 2 - February 2007 1 www.zetex.com © Zetex Semiconductors plc 2007 LM4040 Precision micropower shunt voltage references Description Ordering information The LM4040 is a family of bandgap circuits designed to achieve precision micro-power voltage references of 2.5V and 5.0V. The devices are available in 0.5% C-grade and 1% D-grade initial tolerances. They are available in small outline SOT23 surface mount package which is ideal for applications where space saving is important. Excellent performance is maintained over the 60µA to 15mA operating current 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 pin for pin compatible alternative to the LM4040 voltage reference. Features • Small packages: SOT23 • No output capacitor required • Output voltage tolerance • LM4040C ±0.5% at 25°C • LM4040D ±1% at 25°C • Low output noise (10Hz to 10kHz) .............. 45 VRMS • Wide operating current range 60 A to 15mA • Extended temperature range -40°C to +125°C • Low temperature coefficient 100 ppm/°C (max) Applications • Battery powered equipment • Precision power supplies • Portable instrumentation • Portable communications devices • Notebook and palmtop computers • Data acquisition systems Pinout information 25°C Tol.
