Three-Terminal Low Dropout Voltage Regulator with Output Current of 1 A
The TA48**F/S series consists of fixed-positive-output,
low-dropout regulators with an output current of 1 A (max) that
utilize V-PNP transistors for the output stage. 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
Maximum output current: 1 A
Output voltage accuracy: VOUT ± 3% (@Tj = 25°C)
Low standby current: 800 µA (typ.) (@IOUT = 0 A)
Low starting quiescent current
Low-dropout voltage: VD = 0.5 V (max) (@IOUT = 0.5 A)
Protection function: overheat/overcurrent
Package type: PW-MOLD (TA48**F Series)
TO-220NIS (TA48**S Series)
TA48**F Series has a lead bending type package which is a
surface-mountable package and can be used for reflow
soldering.
