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

Usage Precautions
(1) In regard to GND, be careful not to apply a negative voltage to the input/output terminal.
(2) If a surge voltage exceeding the absolute maximum rating is applied to the input terminal or if a
voltage in excess of the input terminal voltage is applied to the output terminal, the circuit may be
destroyed.
Particular care is necessary in the case of the latter.
Circuit destruction may also occur if the input terminal shorts to GND in a state of normal operation,
causing the output terminal voltage to exceed the input voltage (GND potential) and the electrical
charge of the chemical capacitor connected to the output terminal to flow into the input side.
Where these risks exist, take steps such as connecting Zener and general silicon diodes to the circuit,
as shown in the figure below.
(3) When the input voltage is too high, the power dissipation of the three-terminal regulator, which is a
series regulator, increases, causing the junction temperature to rise. In such a case, it is
recommended to reduce the power dissipation, and hence the junction temperature, by inserting a
power-limiting resistor RSD in the input terminal.
The power dissipation PD of the IC is expressed in the following equation.
Reducing VIN' below the lowest voltage necessary for the IC will cause ripple, deterioration in output
regulation and, in certain circumstances, parasitic oscillation.
To determine the resistance value of RSD, design with a margin, referring to the following equation.
(4) Be sure to connect a capacitor near the input terminal and output terminal between both terminals
and GND. The capacitances should be determined experimentally because they depend on printed
circuit board patterns. In particular, adequate investigation should be made to ensure there is no
problem even in high or low temperatures.
(5) The molded plastic portion of this unit, measuring 5.5 mm (L) by 6.5 mm (W) by 2.3 mm (T), is more
compact compared to its equivalent TO-220.
The collector fin extends directly out of the main body and can be soldered directly to the ceramic
circuit board for significant increase in collector power dissipation.
To obtain high reliability on the heat sink design of a regulator IC, it is generally required to derate
more than 20% of maximum junction temperature (Tj max).
Further, full consideration should be given to the installation of the IC on a heat sink.

Do not apply voltage to the Product that is lower than the minimum operating voltage, or the Product’s
protective functions will not operate properly and the Product may be permanently damaged.
The overcurrent protection circuits in the Product are designed to temporarily protect Product from minor
overcurrent of brief duration. When the overcurrent protective function in the Product activates,
immediately cease application of overcurrent to Product. Improper usage of Product, such as application of
current to Product exceeding the absolute maximum ratings, could cause the overcurrent protection circuit
not to operate properly and/or damage Product permanently even before the protection circuit starts to
operate.
The thermal shutdown circuits in the Product are designed to temporarily protect Product from minor
overheating of brief duration. When the overheating protective function in the Product activates,
immediately correct the overheating situation. Improper usage of Product, such as the application of heat
to Product exceeding the absolute maximum ratings, could cause the overheating protection circuit not to
operate properly and/or damage Product permanently even before the protection circuit starts to operate.
