GNotes on Use

1. Please use this IC within the stipulated absolute maximum ratings as the IC is liable to malfunction outside of such parameters.

2. 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, operations can be stabilised by either increasing the size of CIN or decreasing the size of CL.

3. Please ensure that output current (IOUT) is less than Pd ÷ (VIN -VOUT) and does not exceed the stipulated Continuous Total Power Dissipation

value (Pd) for the package.

4. 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 Torex XC62EP series.
