... Rev. 2/16/98 CS5201-1 The circuit is designed to oper- ate with dropout voltages less than 1. output current. Device protection includes over- current and thermal shutdown. The CS5201 is pin compatible with the LT1086 family of linear regulators. The regulator is available in 2 TO-220, surface mount D , and SOT-223 packages ...

... Stability Considerations section. Adjustable Operation The CS5201-1 has an output voltage range of 1.25V to 5.5V. An external resistor divider sets the output voltage as shown in Figure 1. The regulator maintains a fixed 1.25V (typical) reference between the output pin and the adjust pin ...

... OUT A 22µF tantalum capacitor will work for most applications, but with high current regulators such as the CS5201 the transient response and stability improve with higher val- ues of capacitance. The majority of applications for this regulator involve large changes in load current so the out- put capacitor must supply the instantaneous load current ...

... The value for R based on an average die size. For a high current regulator such as the CS5201-1 the majority of the heat is generated in the power transistor section. The value for R depends on the heat sink type, while R tors such as package type, heat sink interface (is an insula- tor and thermal grease used?), and the contact area between the heat sink and the package ...
