The LT®1963A series are low dropout regulators opTImizedfor fast transient response. The devices are capableof supplying 1.5A of output current with a dropout voltageof 340mV. OperaTIng quiescent current is 1mA, droppingto < 1μA in shutdown. Quiescent current is well controlled;it does not rise in dropout as it does with many otherregulators. In addiTIon to fast transient response, theLT1963A regulators have very low output noise whichmakes them ideal for sensiTIve RF supply applications.Output voltage range is from 1.21V to 20V. The LT1963Aregulators are stable with output capacitors as low as10μF. Small ceramic capacitors can be used without thenecessary addition of ESR as is common with otherregulators. Internal protection circuitry includes reversebattery protection, current limiting, thermal limiting andreverse current protection. The devices are available infixed output voltages of 1.5V, 1.8V, 2.5V, 3.3V and as anadjustable device with a 1.21V reference voltage. TheLT1963A regulators are available in 5-lead TO-220, DD,3-lead SOT-223 and 8-lead SO packages.
