DESCRIPTION
The L4955 is a family of monolithic ultra very low drop linear regulators
designed to supply the most recent microprocessors.
The dropout voltage is only 0.75V (Typ.) at 5A, directly dependent on the
output current conditions. Realized in BCDII technology, it has on board a
charge pump to properly drive an N-channel power mos Transistor with 150mΩ of
RDSON.
It operates from a 4.5V minimum supply, with a very low quiescent current
irrespective of the load; a minimum of 22µF output capacitor is required for
stability.
The on-chip trimming techniques improve the precision of the available output
voltages to ±2%.
