The LT1528CT#PBF is a low-dropout Regulator optimized to handle the large load current transients associated with the current generation of microprocessors. This device has the fastest transient response of currently available PNP regulators and is very tolerant of variations in capacitor ESR. The device has a quiescent current of 400µA. Quiescent current is well controlled and it does not increase significantly as the device enters dropout. The regulator can operate with output capacitors as small as 3.3µF, although larger capacitors will be needed to achieve the performance required in most microprocessor applications. The LT1528 is available with a fixed output voltage of 3.3V. An external SENSE pin allows adjustment to output voltages greater than 3.3V, using a simple resistive divider. This allows the device to be adjusted over a wide range of output voltages, including the 3.3 to 4.2V range required by a variety of processors.
