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 D2PAK 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 varia- tions due to load changes and resis- tive voltage drops. Typical load regulation measured at the sense pin is less than 1mV for an output voltage of 2.5V with a load step of 10mA to 3A. 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, and over-tem- perature protection will self protect the regulator under all fault condi- tions. The CS5253-1 is ideal for generating a secondary 2-2.5V low voltage supply on a motherboard where both 5V and 3.3V are already avail- able. s 1.25V to 5V VOUT at 3A s VPOWER Dropout < 0.40V @ 3A s VCONTROL Dropout < 1.05V @ 3A s 1% Trimmed Reference s Fast Transient Response s Remote Voltage Sensing s Thermal Shutdown s Current Limit s Short Circuit Protection s Drop-In Replacement for Semtech EZ1582 s Backwards Compatible with 3-pin Regulators |
