PRODUCT DESCRIPTION
The AS2880 is a low power 8A Adjustable Voltage Regulator that is very easy to use. It requires only 2 external resistors to set the
output voltage. This device is an excellent choice when using Powering Intel錚?Microprocessor to convert from +5V to 3.3V supplies,
and as a post regulator for switching supplies applications. The AS2880 features low dropout of a maximum 1.5 volts.
The AS2880 offers full protection against over-current faults, reversed input polarity, reversed load insertion, over temperature
operation, and positive and negative transient voltage. On-Chip trimming adjusts the reference voltage to 1%. The I
Q
of this device
flows into the load, which increases efficiency.
The AS2880 is offered in a 3-pin TO-220 package compatible with older 3-terminal regulators. When using ALPHA Semiconductor
design, processing and testing techniques make AS2880 superior over similar products on the market. For a 5A low dropout regulator
refer to the AS2850 datasheet.
