FEATURES  
DESCRIPTIO  
The LT®1461 is a low dropout micropower bandgap refer-  
ence that combines very high accuracy and low drift with low  
supply current and high output drive. This series reference  
usesadvancedcurvaturecompensationtechniquestoobtain  
low temperature coefficient and trimmed precision thin-film  
resistorstoachievehighoutputaccuracy.TheLT1461draws  
only35µAofsupplycurrent,makingitidealforlowpowerand  
portable applications, however its high 50mA output drive  
makes it suitable for higher power requirements, such as  
precision regulators.  
Trimmed to High Accuracy: 0.04% Max  
Low Drift: 3ppm/  
°
C Max  
Low Supply Current: 50  
µA Max  
Temperature Coefficient Guaranteed to 125°C  
High Output Current: 50mA Min  
Low Dropout Voltage: 300mV Max  
Excellent Thermal Regulation  
Power Shutdown  
Thermal Limiting  
Operating Temperature Range: 40°C to 125°C  
Available in SO-8 Package  
In low power applications, a dropout voltage of less than  
300mV ensures maximum battery life while maintaining full  
reference performance. Line regulation is nearly immeasur-  
able, while the exceedingly good load and thermal regulation  
will not add significantly to system error budgets. The  
shutdownfeaturecanbeusedtoswitchfullloadcurrentsand  
can be used for system power down. Thermal shutdown  
protects the part from overload conditions.
