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 theat, oscillation may occur as a result of the impedance present between the power supply and the IC's input. Where impedance is 10W or more, please use a capacitor (C ) IN of at least 1µF. With a large output current, operations can be stabilised by increasing capacitor size (C ). If C is IN IN small and capacitor size (C ) is increased, there is a possibility of oscillation due to input impedance.L In such cases, operations can be stabilised by either increasing the size of C or decreasing the sizeIN of C .L 3. Please ensure the output current (I ) is less than Pd ÷ (V - V ) and does not exceed the OUT IN OUT stipulated continuous total power dissipation value (Pd) for the package. 6251 VIN VO VSSVIN Open Circuit 1 TEST CIRCUIT Circuit 2 6251 VIN VO VSS + +VIN RL1µF (Tantalum) 1µF (Tantalum) V A A FC6251 250mA Ultra-Low Droupout Positive Voltage Regulator FC FC
