L4956
FEATURE DESCRIPTION The L4956 is an adjustable monolithic linear regulator designed to satisfy very heavy load transient and efficient power conversion from 3.3V to 1.26V and lower, up to 5A. TYPICAL APPLICATION MULTIPOWER BCD TECHNOLOGY HEPTAWATT ORDERING NUMBER: L4956 Designed in BCDII technology, it uses a charge pump technique to have a proper internal N-channel 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 150m V gives a voltage drop of 750m V at 5A of load current. Very fast load transients and ±1% of reference voltage precision makes this device suitable for supplying last micrprocessors generation and low voltage logics. The Heptawatt package enriches the device with auxiliary functions like power good and inhibit. INH VPW=3.3Vbus VPW VSIG 1 3 PG 6 7 OUT R1 5 4 GND D96IN374B VSIG= 5Vbus C1 C3 ADJ R2 C2 March...
