The LT1575/LT1577 are single/dual controller ICs that drive low cost external N-channel MOSFETs as source followers to produce ultrafast transient response, low dropout voltage regulators. The LT1575/LT1577 achieve unprecedented transient-load performance by eliminating expensive tantalum or bulk electrolytic output capacitors in the most demanding modern microprocessor applications. Precision-trimmed adjustable and fixed output voltage versions accommodate any required microprocessor power supply voltage. Selection of the N-channel MOSFET RDS(ON) allows very low dropout voltages to be achieved. Unique protection features include a high side current limit amplifier that activates a fault protection timer circuit. A multifunction Shutdown pin provides either current limit time-out with latch off, overvoltage protection, thermal shutdown or a combination of these functions. The LT1575 is available in 8-pin SO or PDIP and the LT1577 is available in 16-pin narrow body SO.
