  advertisement Tracking and Sequencing Made Simple with
  Tiny Point-of-Load Circuit – Design Note 389
  Scott Jackson
  Introduction
  Multiple-voltage electronics systems often require
  complex supply voltage tracking or sequencing, which
  if not met, can result in system faults or even permanent
  failures in the field. The design difficulties in meeting
  these requirements are often compounded in distributedpower architectures where point-of-load (POL) DC/DC
  converters or linear regulators are scattered across PC
  board space, sometimes on different board planes. The
  problem is that power supply circuitry is often the last
  circuitry to be designed into the board, and it must be
  shoehorned into whatever little board real estate is left.
  Often, a simple, drop-in, flexible solution is needed to
  meet these requirements.
  The LTCВ®2927 provides a simple and versatile solution in
  a tiny footprint for both tracking and sequencing without
  the drawbacks of series MOSFETs. Furthermore, power
