GS2911
300mA CMOS Positive LDO Voltage Regulator
Product Description
The GS2911 is a positive voltage output, three-pin regulator that provides a high current even
when the input/output voltage differential is small. Low power consumption and high accuracy
is achieved through CMOS and laser trimming technologies.
The GS2911 consists of a high-precision voltage reference, an error correction circuit, and a
current limited output driver. Transient response to load variations has improved in comparison
to the existing series.
TO-92 and SOT-89 packages are available.
