L4957A
DESCRIPTION
The L4957A devices are Ultra Low Drop Output linear regulators with an internal N-channel MOS of 200mΩ particulary suitable for low voltage/low dropout applications. Operating with a input voltage from 3V to 14V they are capable to deliver up to 5A. The devices are ideal for use as one of the sup-

Fast response transient minimise the output capacitor value. A minimum of 22µF assures the stability in all load conditions. The on-chip trimming technique offers a tighter voltage reference tolerance (with ± 2% including line and load variation) beside to ensure a controlled short circuit current. Thermal shutdown provides protection...
