RC1616
0.5A Adjustable/Fixed Low Dropout Linear Regulator
Features
· · · · · · Low dropout voltage Load regulation: 0.05% typical Current limit On-chip thermal limiting Standard SOT-223 and TO-252 packages Three-terminal adjustable or fixed 2.5V, 3.3V or 5V
Description
The RC1616 and RC1616-2.5, -3.3 and -5 are low dropout three-terminal regulators with 0.5A output current capability. These devices have been optimized for low voltage where transient response and minimum input voltage are critical. The 5V version is designed also to be used in USB Hub and Motherboard applications. On-chip thermal limiting provides protection against any combination of overload and ambient temperature that would create excessive junction temperatures. Unlike PNP type regulators where up to 10% of the output current is wasted as quiescent current, the bias current of the RC1616 flows into the load, increasing efficiency. The RC1616 series regulators are available in the industrystandard SOT-223 and TO-252 power packages.
Applications

Notes: 1. See thermal regulation specifications for changes in output voltage due to heating effects. Load and line regulation are measured at a constant junction temperature by low duty cycle pulse testing. 2. Line and load regulation are guaranteed up to the maximum power dissipation. Power dissipation is determined by input/ output differential and the output current. Guaranteed maximum output power will not be available over the full input/output voltage range. 3. RC1616 only.
