description

The TL461 is a precision series voltage reference with a very low temperature drift of 30 ppm/°C, and
an output voltage tolerance of 0.5%. The TL461 offers a power-saving advantage over three-terminal precision
shunt regulators and voltage references that must conduct the full-load current when operated in the
reverse-breakdown region. In addition, the shutdown feature of the device provides low standby current. This
device is ideal for use with handheld and battery-operated equipment, switching power supplies, dc-dc
converters, A/D and D/A converters, and in low-power precision regulator applications.

The TL461 device is characterized for operation from –40°C to 85°C.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTE 1: Package thermal impedance is calculated in accordance with JESD 51.
