LT3062 45V V , Micropower, IN Low Noise, 200mA LDO Fea T Descrip T n Input Voltage Range: 1.6V to 45V The LT 3062 is a micropower, low dropout (LDO) linear n Output Current: 200mA regulator that operates over a 1.6V to 45V supply range. n Quiescent Current: 45A The device supplies 200mA of output current with a typi- n Dropout Voltage: 300mV cal dropout voltage of 300mV. A single external capacitor n Low Noise: 30V (10Hz to 100kHz) provides programmable low noise reference performance RMS n Adjustable Output (V = 600mV) and output soft-start functionality. The LT3062s quiescent REF n Output Tolerance: 2% Over Load, Line, and current is merely 45A and provides fast transient response Temperature with a minimum 3.3F output capacitor. In shutdown, n Single Capacitor Soft-Starts Reference and Lowers quiescent current is less than 1A and the reference soft Output Noise start capacitor is reset. n Shutdown Current: < 1A The LT3062 optimizes stability and transient response n Reverse Battery Protection with low ESR, ceramic output capacitors. The LT3062 n Current Limit Foldback and Thermal Limit Protection does not require the addition of ESR as is common with n 8-Lead 2mm 3mm DFN and MSOP Packages other regulators. a T Internal protection circuitry includes reverse-battery pro- tection, reverse-output protection, reverse-current protec- n Battery Powered Systems tion, current limit with foldback and thermal shutdown. n Automotive Power Supplies n The LT3062 is available as an adjustable device with an Industrial Power Supplies n output voltage range from the 600mV reference up to 40V. Avionic Power Supplies n The LT3062 is offered in the thermally enhanced 8-lead Portable Instruments 2mm 3mm DFN and MSOP packages.
