FAN1616A

0.5A Adjustable/Fixed Low Dropout Linear Regulator

Features

Description

• Low dropout voltage

• Load regulation: 0.05% typical

• Current limit

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 applica-

tions 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

• Standard SOT-223 and TO-252 packages

• Three-terminal adjustable or ﬁxed 1.8V, 2.5V, 3.3V or 5V

• Speciﬁed from -40°C to +125°C

On-chip thermal limiting provides protection against any

combination of overload and ambient temperature that

would create excessive junction temperatures.

Applications

• USB Controlled Power Supply

• High efﬁciency linear regulators for Mixed Voltage

Logic, ASIC, FPGA based systems

• Post regulators for switching supplies

• Battery chargers

Unlike PNP type regulators where up to 10% of the output

current is wasted as quiescent current, the bias current of the

FAN1616A ﬂows into the load, increasing efﬁciency.

• 12V to 5V, 3.3V, 2.5V, 1.8V, or adj linear regulators

• Motherboard clock supplies

• SDRAM Module supplies

The FAN1616A series regulators are available in the

industry-standard SOT-223 and TO-252 power packages.
