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
into the devices’ output circuit.
Features
• Low stand-by current
• Overtemperature/overcurrent protection
• Operation voltage range is wide.
• Maximum output current is high.
• Difference between input voltage and output voltage is low.
• Small package.
• Ceramic capacitors can be used.

Overtemperature protection and overcurrent protection functions are not necessary guarantee of operating
ratings below the maximum ratings.
Do not use devices under conditions in which their maximum ratings will be exceeded.

• TOSHIBA is continually working to improve the quality and reliability of its products. Nevertheless, semiconductor devices in general
can malfunction or fail due to their inherent electrical sensitivity and vulnerability to physical stress. It is the responsibility of the
buyer, when utilizing TOSHIBA products, to comply with the standards of safety in making a safe design for the entire system, and
to avoid situations in which a malfunction or failure of such TOSHIBA products could cause loss of human life, bodily injury or
damage to property.
In developing your designs, please ensure that TOSHIBA products are used within specified operating ranges as set forth in the
most recent TOSHIBA products specifications. Also, please keep in mind the precautions and conditions set forth in the “Handling
Guide for Semiconductor Devices,” or “TOSHIBA Semiconductor Reliability Handbook” etc..
• The TOSHIBA products listed in this document are intended for usage in general electronics applications (computer, personal
equipment, office equipment, measuring equipment, industrial robotics, domestic appliances, etc.). These TOSHIBA products are
neither intended nor warranted for usage in equipment that requires extraordinarily high quality and/or reliability or a malfunction or
failure of which may cause loss of human life or bodily injury (“Unintended Usage”). Unintended Usage include atomic energy
control instruments, airplane or spaceship instruments, transportation instruments, traffic signal instruments, combustion control
instruments, medical instruments, all types of safety devices, etc.. Unintended Usage of TOSHIBA products listed in this document
shall be made at the customer’s own risk.

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 VCC 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.
