300mA CMOS Positive LDO Voltage Regulator - Globaltech
Description
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.
