Three-Terminal Low Dropout Voltage Regulator with Output Current of 1 A
The TA48**F/S series consists of fixed-positive-output,
(1) TA48**F
low-dropout regulators and V-PNP transistors for output stage
with an output current of 1 A (max). In response to the need for
low-voltage and low-power dissipation devices which are used in
consumer electronics and industrial appliances, the series offers
devices with low output voltages: 1.8 V, 2 V, 2.5 V, 3 V, 3.3 V, 5 V.
Features
l Maximum output current: 1 A
(2) TA48**F (TE16L1, N)
l Output voltage accuracy: V
± 3% (@T = 25°C)
j
OUT
l Low standby current: 800 µA (typ.) (@I
= 0 A)
OUT
l Low starting quiescent current
l Low-dropout voltage: V = 0.5 V (max) (@I
= 0.5 A)
OUT
D
l Protection function: overheat/overcurrent
l Package type: PW-MOLD (TA48**F Series)
TO-220NIS (TA48**S Series)
l TA48**F Series has the lead bending type package which is
the surface-mount package and can be used for reflow
soldering (surface mountable).

Electrical Characteristics for All Products
Generally, the characteristics of power supply ICs change according to temperature fluctuations.
The specification T = 25℃ is based on a state where temperature increase has no effect (assuming no fluctuation
j
in the characteristics) as ascertained by pulse tests.

Connect the input terminal and GND, and the output terminal and GND, by capacitor respectively.
The capacitances should be determined experimentally. In particular, adequate investigation should be made so
that there is no problem even at time of high or low temperature.
