www.fairchildsemi.com FAN1616A 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 xed 1.8V, 2.5V, 3.3V or 5V Specied from -40°C to +125°C Description The FAN1616A, FAN1616A-1.8, -2.5, -3.3 and -5 are low dropout three-terminal regulators with 0.5A output current capability. These devices have been optimized for applications where transient response and minimum dropout 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 FAN1616A ows into the load, increasing efciency. The FAN1616A series regulators are available in the industry-standard SOT-223 and TO-252 power packages. Applications USB Controlled Power Supply High efciency linear regulators for Mixed Voltage Logic, ASIC, FPGA based systems Post regulators for switching supplies Battery chargers 12V to 5V, 3.3V, 2.5V, 1.8V, or adj linear regulators Motherboard clock supplies SDRAM Module supplies Typical Applications FAN1616A VIN = 12V 10F + VIN ADJ VOUT R1 124 + 9V at 0.5A 22F VOUT = VREF(1 + R2/R1) + IAdj R2 R2 768 ……
