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.
