LT1790BCS6-2.5#PBF Datasheet PDF - Linear Technology

The LT1790 series micropower low dropout Voltage Reference combines high accuracy and low drift with low power dissipation. This micropower reference uses curvature compensation to obtain a low temperature coefficient and trimmed precision thin-film resistors to achieve high output accuracy. In addition, each LT1790 is trimmed to greatly reduce the temperature coefficient and increase the output accuracy. Output accuracy is further assured by excellent line and load regulation. Special care has been taken to minimize thermally induced hysteresis. The LT1790s are ideally suited for battery-operated systems because of their small size, low supply current and reduced dropout voltage. This reference provide supply current and power dissipation advantages over shunt references that must idle the entire load current to operate. Since the LT1790 can also sink current, it can operate as a micropower negative voltage reference with the same performance as a positive reference.
