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).

The noise capacitor should be connected to NOISE pin
to GND for stable operation.
The recommended value is higher than 0.0047μF.
The figure above shows commended configuration for using a point regulator. Insert a capacitor for stable
input/output operation.
If the control function is not to be used, Toshiba recommended that the control pin be connected to the
V
CC
pin.

Ripple Rejection
TAR8H06K 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.

NOISE Pin
TAR8H06K device incorporate a NOISE pin to reduce output noise voltage. Inserting a capacitor between
the NOISE pin and GND reduces output noise. To ensure stable operation, insert a capacitor of 0.0047
