To achieve very low dropout, the internal pass transistor is powered separately from the con- trol circuitry. Furthermore, with the control and power inputs tied together, this device can be used in single supply configuration and still offer a better dropout voltage than conventional PNP-NPN based LDO regulators. In this mode the dropout is determined by the mini- mum control voltage. It is supplied in a five-terminal TO-220 package, which allows for the implementation of a remote- sense pin permitting very accurate regulation of output voltage direct- ly at the load, where it counts, rather than at the regulator. This remote sensing feature virtually eliminates output voltage variations due to load changes and resistive voltage drops. Typical load regula- tion measured at the sense pin is 1mV for an output voltage of 2.5V with a load step of 10mA to 10A. The very fast transient loop response easily meets the needs of the latest microprocessors. In addi- tion, a small capacitor on the Adjust pin will further improve the tran- sient capabilities. Internal protection circuitry pro- vides for Òbust-proofÓ operation, similar to three-terminal regulators. This circuitry, which includes over- current, short circuit, supply sequencing and overtemperature protection, will self protect the reg- ulator under all fault conditions. The CS52510-1 is ideal for generat- ing a secondary 2 - 2.5V low voltage supply on a motherboard where both 5V and 3.3V are already available.
