Product Summary

The LTC1798CS8-2.5#TR is a micropower bandgap reference that combine high accuracy and low drift with very low supply current and small package size. The combination of ultralow quiescent current and low dropout voltage of only 200mV (max) makes them ideal for battery-powered equipment. The output voltage is set by an external resistor divider for the adjustable LTC1798. This series of references uses curvature compensation to obtain low temperature coefficient and trimmed thin-film resistors to achieve high output accuracy. These references can source up to 10mA and sink up to 2mA, making them ideal for precision regulator applications. They are stable without an output bypass capacitor, but are also stable with capacitance up to 1mF. This feature is important in critical applications where PC board space is a premium and fast settling is demanded. Applications are notebook and palmtop computers, distributed power systems.
