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 10
Ω 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.
