The 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.

The L4957 devices are Ultra Low Drop Output lin-  
ear regulators with an internal N-channel MOS of

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.  
Operating with a input voltage from 3V to 6.5V  
they are capable to deliver up to 4A at 1.5V or  
2.5V fixed output voltages.
