LT1461

Micropower Precision

Low Dropout Series

Voltage Reference Family

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.
