Texas Instruments TMS77701 Data Sheet
Summary
These low-dropout voltage regulators are high-performance LDOs built for reliable power management in advanced electronic and battery-powered systems. The product offers fast transient response and ultra-low dropout voltage, ensuring stable operation even under demanding load changes. The manual details models featuring integrated Power-On Reset (TPS777xx) or Power Good (PG) output (TPS778xx), providing critical system status signaling. Engineers designing embedded or microcomputer systems will find these regulators ideal for fixed or adjustable outputs ranging from 1.5V to 3.3V, balancing high reliability with excellent efficiency and low quiescent current draw.
