3.0A Positive Voltage Regulator

The XB1085 is a series of low dropout positive voltage regulators with a high output current capacity of 3A.

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 XB1085P series and a voltage adjustable type for XB1085K series. The adjustable type can set the output voltage with two external resistors.

With an overcurrent 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 XB1085 series is available in TO-252 package.
