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.

Note1. VOUT(T) = Specified output voltage.
Note2. VOUT(E) = Effective output voltage (i.e. the output voltage when “ VOUT(T)+1.0V” is provided at the VIN pin while
maintaining a certain IOUT value.)
Note3. Vdif = (VIN 1 (Note 4) – VOUT (E))
Note4. VIN 1 = The input voltage at the time 98% of VOUT(E) is output (input voltage has been gradually reduced).
