LT308x Rugged Single Resistor Linear Regulators

Analog Devices Inc. LT308x single resistor rugged low dropout linear regulators (LDOs) are designed for rugged industrial applications. A key feature of the components is the extended safe operating area (SOA). The LDOs can be paralleled for higher output current or heat spreading. The devices withstand reverse input and reverse output-to-input voltages without reverse current flow. The LT308x precision 50μA 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. These Analog Devices Inc. devices are stable with or without input and output capacitors. Internal protection circuitry includes reverse-battery and reverse-current protection, current limiting and thermal limiting.
