TOSHIBA Bipolar Linear Integrated Circuit
Silicon Monolithic
TAR5S15~TAR5S50
Point Regulators (Low-Dropout Regulator)
The TAR5Sxx Series is comprised of general-purpose bipolar single-power-supply devices incorporating a
control pin which can be used to turn them ON/OFF.
Overtemperature and overcurrent protection circuits are built
in to the devices’ output circuit.

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 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.
