description

LT^®The 3050 Series is a micropower, low noise, low dropout voltage (LDO) linear regulator. The device can deliver 100mA of output current and a dropout voltage of 340mV. A 10nF bypass capacitor reduces output noise to 30μV_RMS(within a 10Hz to 100kHz bandwidth) and soft-start the reference. The LT3050's ±45V input voltage rating and its precise current limit and diagnostic features make the IC ideal for rugged, high reliability systems.

A single resistor sets the current limit of the LT3050 and achieves ±5% accuracy over a wide input voltage and temperature range. Setting the LT3050's minimum output current monitor with a single resistor is useful for detecting open circuit conditions. The current monitor function provides a current equal to 1/100th of the output current. A logic if the LT3050 is in a current limit state, operating below its minimum output current (open), or in a thermal shutdown stateFAULTThe pin will be determined to be low.

The LT3050 optimizes stability and transient response with low ESR ceramic capacitors, requiring a minimum capacitance of 2.2μF. The LT3050 can be used as an adjustable device with an output voltage range as low as 0.6V reference. The LT3050 is available in thermally enhanced 12-lead 3mm × 2mm DFN and MSOP packages.
