AS535

2.5 V Precision Reference / Amplifier Features Description A/AS535 www.DataSheet4U.com Temperature-compensated: 50 ppm/°C Trimmed 0.5% typical bandgap reference High gain Internal amplifier with 100 mA capability Nominal temperature range extended to 105° C Low frequency dynamic output impedance: < 150 mΩ Low output noise Top view The AS535 is a three terminal adjustable shunt regulator utilizing an accurate 2.5V bandgap reference. The AS535 is functionally similar to an AS2431 except that the reference and amplifier operate off of a seperate supply from the output, allowing very low output voltges (0.1V Typically) Because of its robust bipolar technology, the AS535 handles a wide range of current, and holds off up to 18V so its use is not limited to low power, low voltage systems. Significant care has been taken to provide adequate AC bandwidth to allow the AS535 as an amplifier in control systems and power electronics. ASTEC also offers a 1.0% version of this part, the A535.
