CS52510−1
10 A LDO 5−Pin Adjustable
Linear
Regulator
This new very low dropout
regulator is designed to power the next generation of advanced microprocessor. To achieve very low dropout, the internal pass
transistor is powered separately from the control 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 minimum 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 directly 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 regulation measured at the sense pin is 1.0 mV for an output voltage of 2.5 V with a load step of 10 mA to 10 A.
The very fast transient loop response easily meets the needs of the latest microprocessors. In addition, a small capacitor on the Adjust pin will further improve the transient capabilities.
Internal protection circuitry provides for “bust−proof” operation, similar to three−terminal
regulators. This circuitry, which includes overcurrent, short circuit, supply sequencing and overtemperature protection, will self protect the
regulator under all fault conditions.
