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).
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.
Power mold package:
Surface-mount type for reflow soldering is also supported.
