LT3065EDD#PBF, LDO Voltage Regulator, Adjustable, 1.6 V to 45 V in, 0.3 V Dout, 0.5 A, DFN-EP-10

LT®3065 series micropower, low noise, low dropout voltage (LDO) linear regulator. A single external capacitor provides programmable low noise reference performance and output soft-start functionality. A single external resistor programs the LT3065's current limit, accurate to ±10% over a wide input voltage and temperature range. A PWRGD flag indicates output regulation. The LT3065 optimizes stability and transient response with low ESR ceramic capacitors, requiring a minimum of 3.3µF. Internal protection circuitry includes current limiting with foldback, thermal limiting, reverse battery protection, reverse current protection and reverse output protection. Typical applications are battery-powered systems, automotive power supplies, industrial power supplies, avionic power supplies, portable instruments.
