AMS1117-ADJ

0.8A Adjustable/Fixed Low Dropout Linear Regulator� -� Low dropout voltage - Load regulation: 0.2% typical - Optimized for Low Voltage - On-chip thermal limiting - Standard SOT-89 packages - Three-terminal adjustable or fixed low dropout 1.2V,1.5V,1.8V, 1.9V, 2.5V, 3.3V, 5V. Regulators - High efficiency linear regulators - Post regulators for switching supplies - Battery chargers - 12V to 5V linear regulators - Motherboard clock supplies The AMS1117-ADJ and AMS1117-1.2,-1.5,-1.8,-1.9,-2.5 -3.3 and-5.0 are low dropout three-terminal regulators with 0.8A output current capability.These devices have been optimized for low voltage where transient response and minimum input voltage are critical. On-chip thermal limiting provides protection against any combination of overload and ambient temperatures that would create excessive junction temperatures. The AMS1117 series regulators are available in the indus- try-standard SOT-89 packages.
