CM1582
3A LOW DROPOUT VOLTAGE REGULATOR
Output Voltage
The CM1582 adjustable version develops a 1.25V reference voltage between the Sense pin and the Adjust pin (Figure 5). Placing
a resistor between these two terminals causes a constant current to flow through R1 and down through R2 to set the output
voltage. In general R1 is chosen so that this current is the specified minimum load current of 10mA. The current out of the Adjust
pin is small, typically 50uA and it adds to the current for R1. For best regulation the top of the resistor divider should be connected
directly to the Sense pin.
