FEATURES  
DESCRIPTIO  
TheLT®1461isafamilyoflowdropoutmicropowerbandgap  
referencesthatcombineveryhighaccuracyandlowdriftwith  
low supply current and high output drive. These series  
referencesuseadvancedcurvaturecompensationtechniques  
to obtain low temperature coefficient and trimmed precision  
thin-film resistors to achieve high output accuracy. The  
LT1461 family draws only 35µA of supply current, making  
them ideal for low power and portable applications, however  
their high 50mA output drive makes them 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  
Voltage Options: 2.5V, 3V, 3.3V, 4.096V and 5V  
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. The LT1461 is  
available in 2.5V, 3V, 3.3V 4.096V and 5V options.
