L4955 - Brand New STMicroelectronics Non-Rechargeable Batteries
-
Description
The L4955 is a family of monolithic ultra very low drop linear regulators designed to supply the most recent microprocessors. It has a dropout voltage of only 0.75V (Typ.) at 5A and operates from a 4.5V minimum supply. The on-chip trimming techniques improve the precision of the available output voltages to ±2%. The L4955 is realized in BCDII technology and has on-board charge pump to drive an N-channel power mos Transistor with 150mΩ of RDSON. A minimum of 22µF output capacitor is required for stability.
