Linear Regulators  
http://onsemi.com  
The CS5203A series of linear regulators provides 3.0 A at  
adjustable and fixed voltages with an accuracy of ±1.0% and ±2.0%  
respectively. The adjustable version uses two external resistors to set  
the output voltage within a 1.25 V to 13 V range.  
The regulators are intended for use as post regulators and  
microprocessor supplies. 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 CS5203A is pin compatible with the LT1085 family of linear  
regulators but has lower dropout voltage.
