HEPTAWATT PACKAGE  
Designed in BCDII technology, it uses a charge  
pump technique to have a proper internal N-chan-  
nel gate drive. The signal supply voltage input  
VSIG can operate from 4.5V up to an absolute of  
7V and the power supply voltage input VPW can  
opearte from 3V min to an absolute of 7V. An  
RDSON of 150mV gives a voltagedrop of 750mV  
at 5A of load current.  
APPLICATIONS  
PENTIUM AND POWER PC SUPPLIES  
LOW COST SOLUTION FOR 3.3V TO 1.5V  
CONVERSION  
SUITABLE FOR APPLICATIONS WITH  
STAND BY FEATURE  
Very fast load transients and ±1% of reference  
voltage precision makes this device suitable for  
supplying last micrprocessors generation and low  
voltage logics.  
DESCRIPTION  
The L4956 is an adjustable monolithic linear regu-  
lator designed to satisfy very heavy load transient  
and efficient power conversion from 3.3V to 1.26V  
and lower, up to 5A.  
The Heptawatt package enriches the device with  
auxiliary functions like power good and inhibit.
