1.5A Low Dropout Voltage Regulator
Product Description
The GS1086L is a low dropout three-terminal
regulator with 1.5A output current capability. In
order to obtain lower dropout voltage and fast
transient response, this is critical for low voltage
applications. The GS1086L has been optimized.
The device is available in an adjustable version
and fixed output voltage of 1.5V, 1.8V, 2.5V, 3.3V
and 5V. Dropout voltage is guaranteed at a
maximum of 1.3V at 1.5A.
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 would
create excessive junction temperatures.
The GS1086L is available in the three leads
SOT-223, TO-252 and TO-263 surface mount
packages.
