Revision: April 20, 2004
The SC553 is a low dropout linear regulator that
operates from a +2.25V to +6.5V input range and
delivers up to 150mA. A PMOS pass transistor allows
the low 75μA 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 SC553 has an adjust pin (ADJ) enabling the user to
set the output voltage anywhere from 1.25V to 6V. For a
low noise version, see SC1453 and for an error flag see
SC1457. Other features include low powered shutdown,
short circuit protection, thermal shutdown protection and
reverse battery protection. The SC553 comes in the tiny
5 lead SOT-23 package.
