XB1086 Series

1.5A Positive Voltage Regulator

The XB1086 is a series of low dropout positive voltage regulators with a high output current capacity of 1.5A.

Stable output can be maintained by using 10μF (CIN) and 22μF (CL) of tantalum capacitors.

The series is available in 1.5V, 1.8V, 2.5V, 3.3V, and 5.0V types for the XB1086P series and the XB1086K series, which is a voltage adjustable type. The adjustable type can set the output voltage with two external resistors. With an over current and thermal protection circuit built-in, the IC is protected by these circuits operation when an output current reaches limit current or junction temperature increases up to limit temperature.

The XB1086 series is available in TO-252 package.
