Description

The LT 3080 is a 1.1A low dropout linear regulator that can be paralleled to increase output current or spread heat in surface mounted boards. Architected as a The CA3080 and CA3080A are similar in generic form to conventional operational amplifiers, but differ sufficiently to justify an explanation of their unique n Output Current: 1.1A n Single Resistor Programs Output Voltage n 1% Initial Accuracy of SET Pin Current n Output Adjustable to 0V n Low Output Noise: The CA3080 and CA3080A types are Gatable-Gain Blocks which utilize the unique operational-transconductance- amplifier (OTA) concept described in 3 Description. The LM138 series of adjustable 3-terminal positive voltage regulators is capable of supplying in excess of 5 A over a 1.2-V to 32-V output range.
