LT1790AIS6-5#TRPBF

SOT - 23 micropower low dropout series references that combine high accuracy and low drift with low power dissipation and small package size. These micropower references use curvature compensation to obtain a low temperature coefficient and trimmed precision thin - film resistors to achieve high output accuracy. In addition, each is post - package 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. These references are ideally suited for battery - operated systems because of their small size, low supply current and reduced dropout voltage. These references provide supply current and power dissipation advantages over shunt references that must idle the entire load current to operate. Since it can also sink current, it can operate as a micropower negative voltage reference with the same performance as a positive reference.
