■Directions for use
ꢀNotes on Use
1. Please use this IC within the stipulated absolute maximum ratings as the IC is liable to malfunction outside of such parameters. When the
voltage on VOUT is larger than that of VIN, for example, when there are two power supply, please insert schottky diode between VOUT and VIN
not to exceed the rating of VOUT.
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 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, 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.
