TOREX XB1086P501JR

ETR0325-004
■GENERAL DESCRIPTION
The XB1086 is a series of low dropout positive voltage regulators with a high output current capability of 1.5A.
Stable output can be maintained by using 10μF (CIN) and 22μF (CL) of tantalum capacitors.
The XB1086P series is available in the fixed voltage types of 1.5V, 1.8V, 2.5V, 3.3V, and 5.0V. The XB1086K is also
available as a voltage adjustable type which can set the output voltage with only two external resistors. With an over current
and thermal protection circuit built-in, the IC is disabled for protection when an output current reaches limit current or junction
temperature increases up to limit temperature.
The XB1086 series is available in TO-252 package.
