LTC1798CS8-2.5#PBF

LTC1798 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 device. This series of references uses curvature compensation to obtain low temperature coefficient and trimmed thin-film resistors to achieve high output accuracy. This reference can source upto 10mA and sink upto 2mA, making them ideal for precision regulator applications. It is stable without an output bypass capacitor, but are also stable with capacitance upto 1µF. This feature is important in critical applications where PC board space is a premium and fast settling is demanded. It is used in applications such as battery-powered systems, handheld instruments, precision power supplies, A/D and D/A converters.
