XB1085 Series
3.0A Positive Voltage Regulator
The XB1085 series is a 3A low-dropout positive voltage regulator, available with 1.5V, 1.8V, 2.5V, 3.3V, and 5.0V fixed output voltages (XB1085P). An adjustable output voltage variant is also available (XB1085K) where the voltage is set by external resistors. Maximum input voltage is 12V.
A max 3A output current can be generated with a low 1.3V (typ) dropout voltage. The built-in over-current and thermal protection circuits operate when either output current reaches the current limit level or junction temperature limit is reached. The XB1085 series provides stable input and load stability as well as stable temperature variation by using a 10µF tantalum capacitor for the input (CIN) and a 22µF tantalum capacitor for the output (CL).
The XB1085 is available in a TO-252 package.
