Application Note
1. Recommended Application Circuit
The figure above shows the recommended configuration for using a point regulator. Insert a capacitor for
stable input/output operation. If the control function is not to be used, Toshiba recommend that the control pin
(pin 1) be connected to the V
CC
pin.
2. Power Dissipation
The power dissipation for board-mounted TAR5Sxx Series devices (rated at 380 mW) is measured using a
board whose size and pattern are as shown below. When incorporating a device belonging to this series into
your design, derate the power dissipation as far as possible by reducing the levels of parameters such as input
voltage, output current and ambient temperature. Toshiba recommend that these devices should typically be
derated to 70%~80% of their absolute maximum power dissipation value.
