DESCRIPTION
Micropower Low
Dropout References
The LTC
1258/LTC1258-2.5/LTC1258-3/LTC1258-4.1/
LTC1258-5 are micropower bandgap references that
combine high accuracy and low drift with very low sup-
ply current and small package size. The combination of
ultralow quiescent current and low dropout voltage of only
200mV maximum makes them ideal for battery-powered
equipment. The output voltage is set by an external resistor
divider for the adjustable LTC1258.
This series of references uses curvature compensation to
obtain low temperature coefcient and trimmed thin-lm
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 1μF. This feature is important in
critical applications where PC board space is a premium
and fast settling is demanded.
The LTC1258 series references provide power dissipation
advantages over shunt references. In addition to supply
current, shunt references must also idle the entire load
current to operate.
The LTC1258 series is available in the 8-pin MSOP and
SO packages.
