LT1587CT-1.5 Datasheet PDF - Linear Technology

●DESCRIPTION

●The LT ®1587-1.5 is a low dropout 3-terminal regulator with a fixed 1.5V output voltage and 3A output current capability. The design is optimized for low voltage applications where transient response and minimum input voltage are critical. Similar to the LT1085, it has lower dropout and faster transient response. These improvements make it ideal for low voltage microprocessor applications, especially as the regulator in an Intel Pentium Pro processor GTL+ supply.

●Current limit is trimmed to ensure specified output current and controlled short-circuit current. On-chip thermal limiting provides protection against any combination of overload that creates excessive junction temperatures.
