CS52531
3.0 A LDO 5Pin Adjustable
Linear Regulator
This new very low dropout linear regulator reduces total power
dissipation in the application. 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.
The CS52531 is offered in a fiveterminal D
2
PAK5 package,
which allows for the implementation of a remotesense 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 less than 1.0 mV for an output voltage of 2.5 V with a load step
of 10 mA to 3.0 A.
The CS52531 has a very fast transient loop response which can be
adjusted using a small capacitor on the Adjust pin.
Internal protection circuitry provides for “bustproof” operation,
similar to threeterminal regulators. This circuitry, which includes
overcurrent, short circuit, and overtemperature protection will self
protect the regulator under all fault conditions.
The CS52531 is ideal for generating a 2.5 V supply to power
graphics controllers used on VGA cards.
