BL1084 Datasheet | BELLING

DESCRIPTION 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. 5A Bipolar Linear Regulator Features - Fixed and adjustable versions. - Maximum output current : 5A - Maximum input voltage: 15V - Line regulation: 0.2％ (Typical) - Load regulation: 0.2％ (Typical) - On-Chip Thermal Shutdown - Operation environment Temperature: -10℃ ~ 85℃ APPLICATIONS - Power Management for puter Mother Board, Graphic Card - Battery Charger - Post Regulators for Switching Supplies - Microprocessor Supply TYPICAL APPLICATION Fig 1.
