L4957A

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 L4957A devices are ideal for use as one of the sup-plies required by processor,for example they are the cost effective and efficient solution for conver-sion from 3.3V (rail bus) to 2.5V @ 2.5A or to 1.5V with high current rating.

Fast response transient minimise the output ca-pacitor 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 con-trolled short circuit current.Thermal shutdown provides protection against overload conditions that creates excessive junction temperature.
