LINEAR TECHNOLOGY LT3014 Specifications and User Guide
Summary
The LT3014 is a micropower linear regulator engineered for demanding high-voltage and battery-powered systems requiring stable power at only 20mA output. Designed with extreme efficiency in mind, it features an ultra-low quiescent current (as low as 7µA) and operates across a wide input range (3V to 80V). This comprehensive manual provides details on technical specifications, mounting guidelines, package options, and application insights. It is essential reading for electrical engineers designing specialized electronics for mission-critical applications in telecom, automotive, or other high-voltage industrial environments needing reliable power efficiency.

Low Dropout Micropower
Linear Regulator
FEATURES DESCRIPTION n Wide Input Voltage Range: 3V to 80V The LT®3014 is a high voltage, micropower low dropout n Low Quiescent Current: 7µA linear regulator. The device is capable of supplying 20m A of n Low Dropout Voltage: 350m V output current with a dropout voltage of 350m V. Designed n Output Current: 20m A for use in battery-powered or high voltage systems, the low n LT3014HV Survives 100V Transients (2ms) quiescent current (7μA operating and 1μA in shutdown) n No Protection Diodes Needed makes the LT3014 an ideal choice. Quiescent current is n Adjustable Output from 1.22V to 60V also well controlled in dropout. n 1µA Quiescent Current in Shutdown
