LT3086-EP 40V, 2.1A Low Dropout Adjustable Linear Regulator with Monitoring and Cable Drop Compensation FEATURES DESCRIPTION n Wide Input Voltage Range: 1.4V to 40V The LT 3086-EP is a multi-feature, low dropout, low noise n 1 Resistor Sets Output Voltage: 0.4V to 32V 2.1A linear regulator that operates over a 1.4V to 40V input n Output Current: 2.1A supply range. Dropout voltage at 2.1A is typically 330mV. n 1% Tolerance Over Line, Load and Temperature One resistor sets output voltage from 0.4V to 32V. Output n Output Current Monitor: I = I /1000 voltage tolerance is guaranteed to 1% over line, load and MON OUT n Temperature Monitor with Programmable temperature. The LT3086-EP is stable with ceramic output Thermal Limit capacitors, requiring a minimum of 10F. n Programmable Cable Drop Compensation The LT3086-EPs programmable cable drop compensation n Parallel Multiple Devices for Higher Current cancels output voltage errors caused by resistive connec- n Dropout Voltage: 330mV tions to the load. A master/slave configuration allows paral- n 1 Capacitor Soft-Starts Output and Decreases Noise leling of multiple devices for higher load current and heat n Low Output Noise: 40V (10Hz to 100kHz) RMS spreading without external ballast resistor requirements. n Precision, Programmable External Current Limit n Output current and temperature monitoring along with Power Good Flag with Programmable Threshold n a power good flag provide system diagnostic and debug Ceramic Output Capacitors: 10F Minimum n capability. Internal fault circuitry includes thermal shutdown Quiescent Current in Shutdown: <1A n and current limit with foldback. Thermal limit and current Reverse-Battery, -Current and -Output Protection n limit are also externally programmable. Available in 16-Lead TSSOP The LT3086-EP is available in the thermally enhanced 16- Lead TSSOP package.
