CS5253B8
3.0 A LDO 5Pin 2.5 V Fixed
Linear Regulator for
Remote Sense Applications
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 PNPNPN based LDO
regulators. In this mode the dropout is determined by the minimum
control voltage.
The CS5253B8 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 CS5253B8 has a very fast transient loop response.
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 CS5253B8 is ideal for generating a 2.5 V supply to power
graphics controllers used on VGA cards. Its remote sense and low
value capacitance requirements make this a low cost high performance
solution. The CS5253B8 is optimized from the CS52531 to allow a
lower value of output capacitor to be used at the expense of a slower
transient response.
