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.
