SP086 .5A Low Dropout Linear Regulator

© 2006 Sipex Corporation

general Description

The S

P1086 is a series of low dropout positive voltage regulators with a maximum dropout of 1.5V at 1.5A of load

current. The series features on-chip thermal shutdown. It also includes a bandgap reference and a current limiting

circuit. The S

P1086 is available in 1.5V, 1.8V, 2.5V, 3V, 3.3V, and 5.0V versions. The fixed versions integrate the

adjust resistors. It is also available in an adjustable version, which can set the output voltage with only two exter

nal

resistors. The S

P1086 series is available in standard packages of TO-263-3, TO-220, and TO-252.
