LT3014 20mA, 3V to 80V 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: 7A linear regulator. The device is capable of supplying 20mA of n Low Dropout Voltage: 350mV output current with a dropout voltage of 350mV. Designed n Output Current: 20mA for use in battery-powered or high voltage systems, the low n LT3014HV Survives 100V Transients (2ms) quiescent current (7A operating and 1A 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 1A Quiescent Current in Shutdown Other features of the LT3014 include the ability to operate n Stable with 0.47F Output Capacitor with very small output capacitors. The regulators are stable n Stable with Aluminum, Tantalum or Ceramic with only 0.47F on the output while most older devices Capacitors require between 10F and 100F for stability. Small ceramic n Reverse-Battery Protection capacitors can be used without the necessary addition of n No Reverse Current Flow from Output ESR as is common with other regulators. Internal protec- n Thermal Limiting tion circuitry includes reverse-battery protection, current TM Available in 5-Lead ThinSOT and limiting, thermal limiting and reverse current protection. 8-Lead DFN Packages The device is available as an adjustable device with a 1.22V APPLICATIONS reference voltage. The LT3014 regulator is available in the 5-lead ThinSOT and 8-lead DFN packages. n Low Current High Voltage Regulators L, LT, LTC and LTM are registered trademarks of Linear Technology Corporation. n Regulator for Battery-Powered Systems ThinSOT is a trademark of Linear Technology Corporation. n All other trademarks are the property of their respective owners.
