  Introduction
  With each new generation of computing systems, total
  power continues to increase while system voltages
  fall. CPU core voltages and logic supplies below 1.8V
  are now commonplace. Power supplies must not only
  regulate low output voltages but they must also operate
  from low input voltages. A low voltage, low dropout
  linear regulator is an attractive conversion option for
  applications where output currents are in the several
  ampere range. Component count and cost are low in
  comparison to switching regulator solutions, and with
  low input-to-output voltage differentials, efficiencies
  are comparable. MOSFET controller/driver are devices well suited to
  deliver lower output voltages from a supply of 1.8V
  or lower. Each device offers excellent line/load regulation, temperature performance and transient load
  step response.
  Figure 1 illustrates the LT1580 delivering 1.3V at 3A
  (maximum), from a 1.8V input supply. This particular
  conп¬Ѓguration requires a higher voltage supply to bias …
