FEATURES

¥ Temperature-compensated: 30 ppm/¡C ¥ Trimmed 0.4% bandgap reference ¥ Internal amplifier with 150 mA capability ¥ Temperature range: Extended to Ð55 to125¡C ¥ Low frequency dynamic output impedance: < 150 m½ ¥ Low output noise ¥ Robust ESD protection

DESCRIPTION

In the standard shunt configuration, the combination of low temperature coefficient (TC), sharp turn-on characteristics, low output impedance and programmable output voltage make this precision reference a perfect zener diode replacement.
