  1.5A, Negative Regulator Expands Family of CurrentReference Linear Regulators
  Dawson Huang The LT3080, introduced in 2007, represented a new linear regulator architecture featuring
  a current source as reference and a voltage follower for the output amplifier. This new
  architecture has a number of advantages, including easy regulator paralleling for increased
  output current and operation down to zero output voltage. Since the output amplifier always
  operates at unity gain without a resistor-setting divider, bandwidth and absolute regulation
  are constant across the output voltage range. Transient response is independent of output
  voltage and regulation can be specified in millivolts rather than as a percent of output.
  Table 1 summarizes the family of devices
  that use this architecture. The LT3091,
  the latest addition to this family, is a 1.5A
  low dropout negative linear regulator
  featuring adjustable current limit and
  current monitor. The LT3091 is similar
  to the other negative linear regulator in

  regulator with current limitation and
  monitor 0.1ВµF LT3091 the family, the LT3090, but with more
  than double the LT3090’s current rating.
  The LT3091 is useful in high current,
  negative voltage applications requiring
  low noise or precision output. It features
  fast transient response, high PSRR and …
