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.

Notes on Use
1. There is a possibility that oscillation may occur as a result of the impedance present
between the power supply and the IC’s input. Where impedance is 10Ω or more, please
use a capacitor (CIN) of at least 1µF. With a large output current, operations can be
stabilised by increasing capacitor size (CIN). If CIN is small and capacitor size (CL) is
increased, there is a possibility of oscillation due to input impedance. In such cases, either
increasing the size of CIN or decreasing the size of CL can stabilize operations.
2. Please ensure that output current (IOUT) is less than PD + (VIN - VOUT) and does not exceed
the stipulated Continuous Total Power Dissipation value (PD).
3. Should you wish to increase output current (IOUT) and/or have the capability to exceed the
stipulated PD value, using a current boost circuit (similar to the one shown below) is likely
to lead to oscillation. With such applications, we recommend use of a boost type voltage
regulator, such as the GS2911 series.
