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) @IOUT = 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

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).

Standard Application Circuit
• Place CIN as close as possible to the input terminal and GND. Place COUT as close as possible to the output
terminal and GND. Although capacitor COUT acts to smooth the DC output voltage during suspension of
output oscillation or load change, it might cause output oscillation in a cold environment due to increased
capacitor ESR. It is therefore recommended to use a capacitor with small variations temperature sensitivity.
The IC may oscillate due to external conditions (output current, temperature, or the type of the capacitor used).
The type of capacitor required must be determined by the actual application circuit in which the IC is used.
Usage Precautions
• Low voltage
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.
• Overcurrent Protection
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.
• Overheating Protection
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.
• Overvoltage Protection
The overvoltage protection circuits in the Product are designed to temporarily protect Product from minor
overvoltage of brief duration. When the overvoltage protective function in the Product activates,
immediately cease application of overvoltage to Product. Improper usage of Product, such as application of
voltage to Product exceeding the absolute maximum ratings, could cause the overvoltage protection circuit
not to operate properly and/or damage Product permanently even before the protection circuit starts to
operate.
