CS5207−2
7.0 A, 1.5 V Fixed Linear
Regulator
The CS52072 provides 7.0 A at 1.5 V with an accuracy of ±2.0 %.
The regulator is intended for use as an active termination for the
GTL bus on Intel based motherboards. The fast loop response and low
dropout voltage make these regulators ideal for applications where
low voltage operation and good transient response are important.
The circuit is designed to operate with dropout voltages as low as 1.0 V
depending on the output current level. The maximum quiescent current is
only 10 mA at full load.
The regulators are fully protected against overload conditions with
protection circuitry for Safe Operating Area (SOA), overcurrent and
thermal shutdown.
The CS52072 is available in TO220 packages.

2. Load regulation and output voltage are measured at a constant junction temperature by low duty cycle pulse testing. Changes in output
voltage due to thermal gradients or temperature changes must be taken into account seperately.
3. Specifications apply for an external Kelvin sense connection at a point on the output pin 1/4” from the bottom of the package.
4. Dropout voltage is a measurement of the minimum input/output differential at full load.
