LT3062 Series 45V VIN, Micropower, Low Noise, 200mA LDO Features Description Input Voltage Range: 1.6V to 45V Output Current: 200mA Quiescent Current: 45µA Dropout Voltage: 300mV Low Noise: 30µVRMS (10Hz to 100kHz) Adjustable Output (VREF = 600mV) nn Fixed Output Voltages: 3.3V, 5V n Output Tolerance: ±2% Over Load, Line, and Temperature n Single Capacitor Soft-Starts Reference and Lowers Output Noise n Shutdown Current: < 1µA n Reverse Battery Protection n Current Limit Foldback and Thermal Limit Protection n 8-Lead 2mm × 3mm DFN and MSOP Packages The LT®3062 is a micropower, low dropout (LDO) linear regulator that operates over a 1.6V to 45V supply range and is available in a series of fixed output and adjustable versions. The device supplies 200mA of output current with a typical dropout voltage of 300mV. A single external capacitor provides programmable low noise reference performance and output soft-start functionality. The LT3062’s quiescent current is merely 45μA and provides fast transient response with a minimum 3.3μF output capacitor. In shutdown, quiescent current is less than 1μA and the reference soft start capacitor is reset. Applications Internal protection circuitry includes reverse-battery protection, reverse-output protection, reverse-current protection, current limit with foldback and thermal shutdown. n n n n n n n n n n n Battery Powered Systems Automotive Power Supplies Industrial Power Supplies Avionic Power Supplies Portable Instruments The LT3062 optimizes stability and transient response with low ESR, ceramic output capacitors. The LT3062 does not require the addition of ESR as is common with other regulators. The LT3062 is available in fixed output voltages of 3.3V and 5V, and as an adjustable device with an output voltage range from the 600mV reference up to 40V. The LT3062 is offered in the thermally enhanced 8-lead 2mm × 3mm DFN and MSOP packages.
