3V Linear Regulator • Battery Chargers • Active SCSI Terminators • Power Management for Notebook • Battery Powered Instrumentation GENERAL DESCRIPTION TThhee AMS2908 series of adjustable and fixed voltage regulators are designed to provide 800mA output current and to operate down to 1V input-to-output differential.
The dropout voltage of the device is guaranteed maximum 1.
3V at maximum output current, decreasing at lower load currents.
On-chip trimming adjusts the reference voltage to 1%.
Current limit is also trimmed, minimizing the stress under overload conditions on both the regulator and power source circuitry.
The AMS2908 devices are pin compatible with other three-terminal regulators and are offered in the low profile surface mount SOT-223 package and in the TO-252 (DPAK) plastic package.
