CS52510-1 Datasheet, PDF (1/10 Pages) Cherry Semiconductor Corporation – 10A LDO 5-Pin Adjustable Linear Regulator

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.
The CS52510−1 is ideal for generating a secondary 2.0−2.5 V low
voltage supply on a motherboard where both 5.0 V and 3.3 V are
already available.
