LDO offers monitoring, protection and cable drop compensation
1 min read
Extending its LDO+ family, Linear Technology has introduced a 40V<sub>IN</sub>, 2.1A rail to rail linear regulator.
The LT3086 includes current monitoring with externally settable current limit and temperature monitoring with external control of thermal limit temperature.
It also includes a programmable power good status flag, cable drop compensation and easy paralleling.
A single resistor programs output voltage from 0.4 to 32V and dropout voltage is only 330mV at 2.1A. The LT3086 is designed to achieve line and load regulation of 0.1%, independent of output voltage.
The trimmed, precision 50µA current reference is ±1% accurate, providing ±2% output voltage tolerance over line, load and temperature. Output voltage regulation, bandwidth, transient response and noise (40µVRMS) remain independent of output voltage due to the device's unity gain voltage follower architecture.
The LT3086 is offered in a variety of thermally enhanced surface mount packages, including a low profile, 16 lead 4 x 5mm DFN, a 16 lead thermally enhanced TSSOP and a 7 lead DD-Pak. All dissipate 2W in surface mount applications with no heat sink.
