... Micropower 5V, 150mA Low Dropout Description The CS8321 is a precision 5V micropower voltage regulator with very low quiescent current (140µA typ at 1mA load). The 5V output is accurate within ±2% and supplies 150mA of load current with a typi- cal dropout voltage of only 300mV. This combination of low quiescent ...

... In some cases, none of the packages will be sufficient to dissipate the heat generated by the IC, and an external heatsink will be required CS8321 I Q Figure 4: Single output regulator with key performance parameters labeled. A heatsink effectively increases the surface area of the package to improve the flow of heat away from the IC and into the surrounding air ...
