LT3065 Series 45V V , 500mA Low Noise, IN Linear Regulator with Programmable Current Limit and Power Good FEATURES DESCRIPTION n Input Voltage Range: 1.6V to 45V The LT 3065 Series are micropower, low noise, low dropout n Output Current: 500mA voltage (LDO) linear regulators that operate over a 1.6V n Dropout Voltage: 300mV to 45V input voltage range. The devices supply 500mA of n Programmable Precision Current Limit: 10% output current with a typical dropout voltage of 300mV. A n Power Good Flag single external capacitor provides programmable low noise n Low Noise: 25V (10Hz to 100kHz) reference performance and output soft-start functionality. RMS n Adjustable Output (V = V = 600mV) REF OUT(MIN) A single external resistor programs the LT3065s current n Output Tolerance: 2% Over Line, Load and limit, accurate to 10% over a wide input voltage and tem- Temperature perature range. A PWRGD flag indicates output regulation. n Stable with Low ESR, Ceramic Output Capacitors The LT3065 optimizes stability and transient response (3.3F Minimum) n with low ESR ceramic capacitors, requiring a minimum of Single Capacitor Soft-Starts Reference and Lowers 3.3F. Internal protection circuitry includes current limiting Output Noise n with foldback, thermal limiting, reverse battery protection, Current Limit Foldback Protection n reverse current protection and reverse output protection. Shutdown Current: <1A n Reverse Battery and Thermal Limit Protection The LT3065 is available in fixed output voltages of 1.2V, n 10-Lead 3mm 3mm DFN and 12-lead MSOP 1.5V, 1.8V, 2.5V, 3.3V, and 5V, and as an adjustable de- Packages vice with an output voltage range from 0.6V to 40V. The LT3065 is available in the thermally-enhanced 10-lead APPLICATIONS 3mm 3mm DFN and 12-lead MSOP packages. n All registered trademarks and trademarks are the property of their respective owners.
