一,产品概述(General Description)
The CXLD64008 series are highly accurate, low noise,LDO Voltage Regulators that are capable of providing an output current that is in excess of 1A with a maximum dropout voltage of 1.3V at 1A ( CXLD64008A33) .This series contains four fixed output voltages of 1.2V, 1.8V, 2.5V and 3.3V that have no minimum load requirement to maintain regulation.On chip trimming adjusts the reference/output voltage to within ±2% accuracy.Internal protection features consist of output current limiting, safe operating area compensation,and thermal shutdown.
The CXLD64008series can operate with up to 18V input. Devices are available in SOT223.

Applications Information
1. Input Bypass Capacitor
An input capacitor is recommended. A 10uF tantalum on the input is a suitable input bypassing for almost all applications.
2. Output Capacitor
The output capacitor is critical in maintaining regulator stability, and must meet the required conditions for both minimum amount of capacitance and ESR (Equivalent Series Resistance).The minimum output capacitance required by the CXLD64008 is 10μF,if a tantalum capacitor is used. Any increase of the output capacitance will merely improve the loop stability and transient response. The ESR of the output capacitor should be less than 0.5Ω .
3. Load Regulation
The CXLD64008 regulates the voltage that appears between its output and ground pins, or between its output and adjust pins. In some cases, line resistances can introduce errors to the voltage across the load. To obtain the best load regulation, a few precautions are needed. Figure1, shows a typical application using a fixed output regulator. The Rt1 and Rt2 are the line resistances. It is obvious that the VLOAD is less than the VOUT by the sum of
the voltage drops along the line resistances. In this case, the load regulation seen at the RLOAD would be degraded from the datasheet specification. To improve this , the load should be tied directly to the output terminal on the positive side and directly tied to the ground terminal on the negative side.
