■GENERAL DESCRIPTIO N

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 out put curre nt reach es limit current or junction temperature increases up to limit temperature.

The XB1086 series is available in TO-252
