Application Notes
1. Recommended Application Circuit
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.

3. Ripple Rejection
The TAR5SxxU feature a good power supply ripple rejection and input transient response, making them an
ideal solution for the RF block of cell phones.
4. NOISE Pin
The TAR5SxxU have a pin named NOISE. To reduce the output noise and ensure stable operation, a
capacitor should be inserted between the NOISE pin and GND. The capacitance value should be at least
0.0047 μF.
The output voltage rise time varies with the value of the capacitor connected to the NOISE pin.
