BL1084-CY

BL1084 is a series of low dropout three terminal regulators with a typical dropout voltage of 1.4V at 5A load current. Other than fixed voltage versions (1.8V, 2.5V, 3.3V, 5.0V), BL1084 has an adjustable voltage version, with which desired voltage can be achieved by setting the values of two external resistors of the application circuitry. BL1084 offers thermal shut down and current limit functions to assure the stability of chip and power system. BL1084 series is available in standard packages of TO - 263 - 2L, TO - 263 - 3L, TO - 220 and TO - 252. BL1084 is a series of low dropout voltage three terminal regulators. Its circuit has a trimmed bandgap reference to ensure output voltage accuracy independent of temperature variance. On - chip thermal shutdown provides protection against overload and conditions as elevated ambient temperature. Its application circuitry requires minimum number of external components. Both fixed voltage and adjustable voltage versions need input and output capacitors to assure output voltage stability. Any desired output voltage from 1.25V to 10V can be achieved with adjustable version by assigning proper values to two external resistors in its application circuitry.
