Overview
LT1575/LT1577 Ultrafast Transient Response, Low Dropout Regulators Adjustable and Fixed FEATURES s s s DESCRIPTION The LT®1575/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 transientload 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 latchoff, overvoltage protection, thermal shutdown or a combination of these functions.
