Three-Terminal Low Dropout Voltage Regulator
The TA48M
**
F series consists of fixed-positive-output, low
dropout regulators with an output current of 500 mA (max). In
response to the need for low voltage devices, the series offers
devices with low output voltages of 2.5 V, 3.3 V etc.
Features
• Maximum output current of 0.5 A
• Low standby current: 800 μA (typ.)
• Low dropout voltage: 0.65 V (max) @I
OUT
= 0.5 A
• Protection function:
overcurrent/overheat/overvoltage/reversed power supply
connections.
• New PW-Mold package (Surface-mount type)

Note 2: The “**” part of each product number varies according to the output voltage of the product.
The product(s) in this document (“Product”) contain functions intended to protect the Product from
temporary small overloads such as minor short-term overcurrent, overvoltage, 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).
