Output Current of 3A, 5A or 7. Product Details The LT1083 series of positive adjustable regulators are designed to provide 7. 5A, 5A and 3A ldo ripple higher efficiency than currently available devices.
All internal circuitry is designed to operate down to 1V input-to-output differential and the dropout voltage is fully specified as a function of load current. Dropout is guaranteed at a maximum of 1. LT1085 devices are pin compatible with older 3-terminal regulators. A 10μF output capacitor is required on these new devices. However, this is included in most regulator designs. LT1083 quiescent current flows into the load, increasing efficiency.

Is your medical device design truly secured? In a world that runs on battery power, the ability to drastically lower power consumption during standby or sleep modes is no longer a luxury.
This is especially true in mobile medical applications that have extended use between charging cycles. A low-dropout or LDO regulator is a DC linear voltage regulator that can regulate the output voltage even when the supply voltage is very close to the output voltage. The adjustable low-dropout regulator debuted on April 12, 1977 in an Electronic Design article entitled “Break Loose from Fixed IC Regulators”. One input of the differential amplifier monitors the fraction of the output determined by the resistor ratio of R1 and R2. The main difference between LDO and non-LDO regulators is their schematic topology.
If a bipolar transistor is used, as opposed to a field-effect transistor or JFET, significant additional power may be lost to control it, whereas non-LDO regulators take that power from voltage drop itself. Because the power control element functions as an inverter, another inverting amplifier is required to control it, which increases schematic complexity compared to simple linear regulator. Power FETs may be preferable to reduce power consumption, but this poses problems when the regulator is used for low input voltage, as FETs usually require 5 to 10 V to close completely. Power FETs may also increase the cost. It is important to keep thermal considerations in mind when using a low drop-out linear regulator.
