Description

General part information

LT3050 Series

The LT3050 series are micro-power, low noise, low dropout voltage (LDO) linear regulators. The devices supply 100mA of output current with a dropout voltage of 340mV. A 10nF bypass capacitor reduces output noise to 30μVRMSin 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 logicFAULTpin 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 in fixed output voltages of 3.3V and 5V, and as an adjustable version 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.ApplicationsProtected Antenna SuppliesAutomotive TelematicsIndustrial Applications (Trucks, Forklifts, etc.)High Reliability Applications
