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.

The SC8863 output voltage can be preset or adjusted

with an external resistor divider. Other features include

low powered shutdown, short circuit protection, thermal

shutdown protection and reverse battery protection.

The SC8863 comes in the tiny 5 lead SOT-23

package.
