TA78M12SB, TA78M15SB, TA78M18SB, TA78M20SB, TA78M24SB
Output Current of 0.5 A, Three-Terminal Positive Voltage Regulators
5 V, 6 V, 8 V, 9 V, 10 V, 12 V, 15 V, 18 V, 20 V, 24 V
The TA78M××SB series of fixed-voltage monolithic integrated
circuit voltage regulators is designed for a wide range of
applications. These regulators employ internal current-limiting,
thermal-shutdown and safe-area compensation, making them
essentially indestructible. One of these regulators can drive up to
0.5 A of output current.
Features
z Suitable for CMOS, TTL and the power supply of other digital
ICs
z Maximum output current of 0.5 A.
SIP3-P-2.50A
z Internal thermal overload protection.
Weight: 1.5 g (typ.)
z Internal short circuit current limiting.
z Package in the plastic case TPL (PD = 1.8 W).

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).

Precautions on Application
(1)
In regard to GND, be careful not to apply a negative voltage to the input/output terminal.
Further, special care is necessary in the case of a voltage boost application.
(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.
