applications requiring fast transient
response are ideally suited for this
product family. The LX8586A is
guaranteed to have < 1.1V at 6A and
the LX8586 < 1.3V at 6A dropout
voltage, making them ideal to provide
well-regulated outputs of 2.5V to 3.6V
using a 5V input supply. Fixed
versions

... O V UTPUT OLTAGE The LX8586/86A ICs develop a 1.25V reference voltage between the output and the adjust terminal (See Figure 2). By placing a resistor, R1, between these two terminals, a constant current is caused to flow through R1 and down through R2 to set the overall output voltage. Normally this current is the specified minimum load current of 10mA ...
