NOT RECOMMENDED FOR NEW DESIGN SC553
150mA Ultra Low Dropout
Regulator with Adjustable Output
POWER MANAGEMENT
Description
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.
Features
! “5205” compatible pinout
! 2% output accuracy guaranteed over line, load and
temperature
! Guaranteed 150 mA output current
! Very small external components - designed to work
with ceramic capacitors
! Output adjustable from 1.25V to 6V
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
