XB1086 Series
1.5A Positive Voltage Regulator
ETR0325-008
■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.

Note:
(*1) O.T. denotes the specifications which apply over the range of operating junction temperature (0℃≦Tj≦125OC).
Please be sure that the power consumption does not exceed the power dissipation rating, 1300mW. If the power consumption
exceeds the power dissipation rating and the operating junction temperature rises more than the rating, 125OC, the IC enters thermal
shutdown state.
■OUTPUT VOLTAGE ADJUSTMENT
With the adjustable XB1086K12BJR, a 1.25V reference voltage is fixed between the VOUT pin and the ADJ pin and the external
resistors R1 and R2 are used to set the output voltage.
Please set it so that an electric current (IR1) flowing through R1 is as above 5mA.
The output voltage is given by the following equation.
