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 V, 3.3 V, 3.45 V, and 4
V, which are not included in the existing TA78DM
**
S series (0.5
A low dropout).
TA48M**F (S)
Features
•
•
•
•
Maximum output current of 0.5 A
Low standby current: 0.8 mA (typ.)
Low dropout voltage: 0.65 V (max) @I
OUT
=
0.5 A
Protection function:
overheat/overcurrent/overvoltage/reversed power supply
connections.
PW-Mold package:
Surface-mount type for reflow soldering is also supported.

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).
