ANALOG DEVICES LT1461CIS8-4#PBF Voltage Reference, Series, 4 V, 12ppm/°C, 0.08%, -40 °C to 85 °C, NSOIC-8

LT1461CIS8-4#PBF is a low dropout micropower bandgap reference that combine very high accuracy and low drift with low supply current and high output drive. This reference uses advanced curvature compensation techniques 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 it ideal for low power and portable applications, however their high 50mA output drive makes them suitable for higher power requirements, such as precision regulators. In low power applications, a dropout voltage of less than 300mV ensures maximum battery life while maintaining full reference performance. Line regulation is nearly immeasurable, while the exceedingly good load and thermal regulation will not add significantly to system error budgets. Applications include A/D and D/A converters, precision regulators, handheld instruments, power supplies.
