LT3010/LT3010-5 50mA, 3V to 80V Low Dropout Micropower Linear Regulator FEATURES DESCRIPTION n Wide Input Voltage Range: 3V to 80V The LT 3010 is a high voltage, micropower low dropout n Low Quiescent Current: 30A linear regulator. The device is capable of supplying 50mA n Low Dropout Voltage: 300mV output current with a dropout voltage of 300mV. Designed n Output Current: 50mA for use in battery-powered or high voltage systems, the n Thermally Enhanced 8-Lead MSOP Package low quiescent current (30A operating and 1A in shut- n No Protection Diodes Needed down) makes the LT3010 an ideal choice. Quiescent cur- n Fixed Output Voltage: 5V (LT3010-5) rent is also well controlled in dropout. n Adjustable Output from 1.275V to 60V (LT3010) Other features of the LT3010 include the ability to oper- n 1A Quiescent Current in Shutdown ate with very small output capacitors. The regulators n Stable with 1F Output Capacitor are stable with only 1F on the output while most older n Stable with Aluminum, Tantalum or Ceramic devices require between 10F and 100F for stability. Capacitors Small ceramic capacitors can be used without the neces- n Reverse-Battery Protection sary addition of ESR as is common with other regula- n No Reverse Current Flow from Output tors. Internal protection circuitry includes reverse-battery n Thermal Limiting protection, current limiting, thermal limiting and reverse n AEC-Q100 Qualified for Automotive Applications current protection. The device is available in a fixed output voltage of 5V and APPLICATIONS as an adjustable device with a 1.275V reference voltage. n Low Current High Voltage Regulators The LT3010 regulator is available in the 8-lead MSOP n Regulator for Battery-Powered Systems package with an exposed pad for enhanced thermal han- n Telecom Applications dling capability. n Automotive Applications All registered trademarks and trademarks are the property of their respective owners.
