... March 1, 2000 DESCRIPTION The SC8863 is a low dropout linear regulator that operates from a +2.5V to +5.5V input range and delivers up to 150mA. A PMOS pass transistor allows the low 110µA supply current to remain independent of load, making these devices ideal for battery operated portable equipment such as cellular phones, cordless phones and personal digital assistants ...

... J APPLICATIONS INFORMATION Theory Of Operation The SC8863 is intended for applications where very low dropout voltage, low supply current and low output noise are critical. It provides a very simple, low cost solution that uses very little pcb real estate. Fixed out- put voltage options require the use of only two external capacitors for operation ...
