LT3088IST#PBF

LT3088 is a single resistor rugged linear regulator designed for rugged industrial applications. A key feature of the IC is the extended safe operating area (SOA). This can be paralleled for higher output current or heat spreading. The device withstands reverse input and reverse output-to-input voltages without reverse current flow. Its precision reference current source allows a single resistor to program output voltage to any level between zero and 34.5V. The current reference architecture makes load regulation independent of output voltage. It is stable with or without input and output capacitors. Internal protection circuitry includes reverse-battery and reverse-current protection, current limiting and thermal limiting. Typical applications are all surface mount power supply, rugged industrial power supply, post regulator for switching supplies, low output voltage supply, intrinsic safety applications.
