SA1085
3A LDO VOLTAGE REGULATOR
DESCRIPTION
The SA1085 is a positive voltage regulator with low dropout
voltage of 1.18V at 3A.
SA1085 provides two versions: fixed and adjustable versions.
VOUT of fixed version has a tolerance of less than 1% for five kinds
of output voltages 1.5V, 1.8V, 2.5V, 3.3V, and 5.0V.
The SA1085 offers some key features include thermal shutdown
and current limiting .The SA1085 is an excellent choice for use in
battery powered applications and portable computers.
