... PMOS power transistor, and resistors for setting output voltage, and current limit and temperature limit protection circuits. The SE5509B has been designed to be used with low cost capacitors and requires a minimum output capacitor of 1.0μF. The output voltages range from 1.3V to 4.4V in 100mV increments. ...
