LT1461 family of low dropout micropower bandgap references combine very high accuracy and low drift with low supply current and high output drive.
The LT1461 series provides high‑accuracy, low‑drift voltage references for applications such as A/D and D/A converters, precision regulators, handheld instruments and power supplies. The devices are trimmed to 0.04 % accuracy, feature a low temperature coefficient of 3 ppm/°C, and consume only 50 µA while delivering up to 50 mA output current.
Electrical characteristics include a maximum dropout voltage of 300 mV, an operating temperature range from –40 °C to 125 °C, and selectable output voltages of 2.5 V, 3 V, 3.3 V, 4.096 V and 5 V. Typical performance graphs and package dimensions are provided for design integration.
