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).

A noise-damping capacitor should be connected between the NOISE pin and GND
for stable operation. The recommended value is higher than 0.0047
μF.
CONTROL GND
NOISE
The above figure shows the recommended application circuit for the TAR5SxxU. Capacitors should be
connected to V
IN
and V
OUT
for input/output stabilization.
If on/off control is not required, it is recommended to connect the CONTROL pin (pin 1) to V
CC
.
2. Power Dissipation
The power dissipation rating (450 mW) is measured on a board shown below. More power can be safely
dissipated by reducing the input voltage, output current and/or ambient temperature. It is recommended to
use the TAR5SxxU at 70% to 80% of the absolute maximum power dissipation.
