Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even
if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum
ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).

Ripple Rejection
TAR8H02K feature a circuit with an excellent ripple rejection characteristic. Because the circuit also
features an excellent output fluctuation characteristic for sudden supply voltage drops, the circuit is ideal for
in the RF blocks incorporated in all mobile telephones.
