Note: To prevent oscillation, a 1µF minimum X7R or X5R dielectric is strongly recommended if ceramics are

used as input/output capacitors. When using the Y5V dielectric, the minimum value of the input/output

capacitance that can be used for stable over full operating temperature range is 3.3µF. (see Application

Information Section for further details)
