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.

The product(s) in this document (“Product”) contain functions intended to protect the Product from
temporary small overloads such as minor short-term overcurrent or overheating. The protective
functions do not necessarily protect Product under all circumstances. When incorporating Product into
your system, please design the system (1) to avoid such overloads upon the Product, and (2) to shut
down or otherwise relieve the Product of such overload conditions immediately upon occurrence. For
details, please refer to the notes appearing below in this document and other documents referenced in
this document.

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).
