... Adjustable Linear Regulator Description The CS5201-1 linear regulator provides 1A with an output voltage accuracy of ±1%. The device uses two external resis- tors to set the output voltage within a 1.25V to 5.5V range. This regulator is intended for use as a post regulator and microprocessor supply. The fast ...

... 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 ...

... The discharge current depends on the value of the capaci- tor, the output voltage and the rate at which V the CS5201-1 linear regulator, the discharge path is through a large junction and protection diodes are not usu- ally needed. If the regulator is used with large values of output capacitance and the input voltage is instantaneous- ly shorted to ground, damage can occur ...

... 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 ...
