... CS52015-1 The circuit is designed to operate with dropout voltages less than 1.4V at 1.5A output current. Device protection includes overcurrent and thermal shutdown. The CS52015-1 is pin compatible with the LT1086 family of linear regulators but has lower dropout voltage. The regulator is available in TO- 2 220, surface mount D , and SOT-223 packages ...

... The CS52015-1 linear regulator provides adjustable volt- ages at currents up to 1.5A. The regulator is protected against overcurrent conditions and includes thermal shutdown. The CS52015-1 has a composite PNP-NPN output transistor and requires an output capacitor for stability. A detailed procedure for selecting this capacitor is included in the Stability Considerations section. ...

... OUT A 22µF tantalum capacitor will work for most applications, but with high current regulators such as the CS52015-1 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 result can be substituted in equation (1). The value for R tor such as the CS52015-1 the majority of the heat is gener- ated 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 ...
