1 / 7 page L4957A UP TO 5A ULDO LINEAR REGULATOR PRODUCT PREVIEW 1.5V, 1.8V, 2.5V AND 3.3V FIXED OUTPUT VOLTAGE 3V TO 14V INPUT VOLTAGE RANGE 200m Ω Rdson TYPICAL @ Tj = 125°C 0.6V max. DROP-OUT AT 2A EXCELLENT LOAD REGULATION 0.6mA QUIESCENT CURRENT AT ANY LOAD SHORT CIRCUIT PROTECTION THERMAL SHUTDOWN APPLICATIONS MOTHER BOARDS PROCESSOR I/O & SUPPLIES LOW VOLTAGE MEMORY & CHIP SET SUP- PLIES GRAPHIC & SOUND CARDS LOW VOLTAGE LOGIC SUPPLIES POST REGULATOR FOR SMPS DESCRIPTION The L4957A devices are Ultra Low Drop Output linear regulators with an internal N-channel MOS of 200m Ω 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- 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 22 µF 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. This is preliminary information on a new product now in development. Details are subject to change without notice.
