SLR1117

Description:

The SLR1117 is a low dropout, three terminals regulator designed to provide output current up to

800mA. The device is available in an adjustable version and fixed output voltage of1.8V, 2.5V and 3.3V.

Dropout voltage of maximum of 1.4V is guaranteed at 800mA output current. The quality of low

dropout voltage and fast transient response make this device ideal for low voltage microprocessor

applications.

The SLR1117 requires output capacitance of a minimum of 10μF for stability. Built-in output current

limiting and thermal limiting provide maximal protection to the SLR1117 against fault conditions.
