The device supplies 100mA of output current with a dropout voltage of 340mV. A 10nF bypass capacitor reduces output noise to 30μVRMS in a 10Hz to 100kHz bandwidth and soft-starts the reference. The LT3050’s ±45V input voltage rating combined with its precision current limit and diagnostic functions make the IC an ideal choice for robust, high reliability applications. A single resistor programs the LT3050’s current limit, accurate to ±5% over a wide input voltage and temperature range. A single resistor programs the LT3050’s minimum output current monitor, useful for detecting open-circuit conditions. The current monitor function sources a current equal to 1/100th of output current. A logic FAULT pin asserts low if the LT3050 is in current limit, operating below its minimum output current (open-circuit) or is in thermal shutdown. The LT3050 optimizes stability and transient response with low ESR ceramic capacitors, requiring a minimum of 2.2μF. The LT3050 is available as an adjustable device with an output voltage range down to the 0.6V reference. The LT3050 is available in the thermally-enhanced 12-Lead 3mm × 2mm DFN and MSOP packages.
