minal Integrated Switching Regulators
(ISRs) designed for pin compatibility
with linear regulators. These ISRs can
be used in a wide variety of on-board
power regulation applications includ-
ing computer, data storage, industrial
controls, medical, and battery powered
equipment. The series of ISRs has
excellent line and load regulation and
laser-trimmed output voltage.
