XB1085 is a series of low dropout positive voltage regulators with a high output current capacity of 3.0A . Stable output can be maintained by using 10μF (CIN) and 22μF (CL) of tantalum capacitors. The fixed voltage types (XB1085P series) are available in 1.5V, 1.8V, 2.5V, 3.3V, and 5.0V. The voltage adjustable type (XB1085K series) is also available which can set the output voltage with only two external resistors. With an overcurrent 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 XB1085 series is available in TO-252 package.
The XB1085 series from Torex are low‑dropout positive voltage regulators available in fixed‑output (XB1085P) and adjustable (XB1085K) versions. They deliver up to 3.0 A output current, support a range of output voltages (1.5 V to 5.0 V), and include built‑in over‑current and thermal protection. The devices are supplied in a TO‑252 surface‑mount package and are RoHS‑compliant.
Typical application circuits show use in battery chargers, DVD drives, set‑top boxes and other battery‑powered equipment. Electrical characteristics such as dropout voltage, line and load regulation, reference accuracy and temperature stability are provided for both fixed and adjustable variants.
