FEATURES  
DESCRIPTIO  
200mV Max Dropout at 10mA Output Current  
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 supply  
currentandsmallpackagesize.Thecombinationofultralow  
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 LTC1258.  
4µA Typical Quiescent Current  
0.15% Max Initial Accuracy (S8)  
No Output Capacitor Required  
Output Sources 10mA, Sinks 2mA  
40ppm/°C Max Drift (S8)  
Available in Small MSOP Package  
Voltage Options: 2.5V, 3V, 4.1V, 5V and Adjustable  
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  
stablewithcapacitanceupto1µF.Thisfeatureisimportant  
incriticalapplicationswherePCboardspaceisapremium  
and fast settling is demanded.

APPLICATIO S  
Battery-Powered Systems  
Handheld Instruments  
Precision Power Supplies  
A/D and D/A Converters  
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.
