DESIGN FEATURES Power Supply Tracking for
Linear Regulators
Introduction (see вЂњVersatile Power Supply Tracking
without MOSFETsвЂќ from Linear Technology Magazine, February, 2004 ) but
it is easily adapted to linear regulators,
including popular low-dropout (LDO)
types. Summarized here are several
techniques for controlling linear regulators with the LTC2923. The LTC2923 provides simple and
versatile control over the power-up
and power-down behavior of switching
power supplies. It allows several supplies to track the voltage of a master
supply, so that their relative voltages
meet the stringent speciп¬Ѓcations for
the power up of modern digital
semiconductors, such as DSPs, microprocessors, FPGAs and ASICs. The
LTC2923 is speciп¬Ѓcally designed to
work with switching power supplies Monolithic Regulators
Table 1 lists three popular monolithic
linear regulators that have been tested
with the LTC2923. Using these three Table 1. New monolithic linear regulators Regulator IOUT(MAX) (V) VIN(MIN) (V) VIN(MAX) (V) VDROPOUT (V) LT3020 100mA 0.9 10 0.15 LTC1844 150mA 1.6 6.5 0.11 LTC3025 300mA 0.9 5.5 0.045 3.3V IN
