The LTC
1798/LTC1798-2.5/LTC1798-3/LTC1798-4.1/
LTC1798-5 are micropower bandgap references that com-
bine 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 refer-
ences 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 1
μ
F. This feature is important
in critical applications where PC board space is a premium
and fast settling is demanded.
The LTC1798 series references provided power dissipa-
tion advantages over shunt references. In addition to
supply current, shunt references must also idle the entire
load current to operate.
The LTC1798 series is available in the SO-8 package.
