description

®The LT 3050 Series is a low-power, low-noise, low-dropout voltage (LDO) linear regulator. The device provides an output current of 100mA and a dropout voltage of 340mV. A 10nF bypass capacitor reduces output noise to 30μVRMS (within a 10Hz to 100kHz bandwidth) and soft-start the reference. The LT3050's ±45V input voltage rating, along with its precise current limiting and diagnostics, make it an ideal choice for rugged, high-reliability systems.

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

The LT3050 utilizes low ESR ceramic capacitors to optimize stability and transient response, 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 a thermally enhanced 12-pin 3mm x 2mm DFN and MSOP package.
