Linear Technology LT3010 Manuals

The LT3010/LT3010-5 is a low dropout linear regulator with a wide input voltage range of 3V to 80V. It features low quiescent current, low dropout voltage, and stability. The LT3010-5 has a fixed output voltage of 5V, while the LT3010 can adjust the output voltage from 1.275V to 60V. The regulator is equipped with various protection functions, including reverse-battery protection, current limiting, and thermal limiting.

The LT3010/LT3010-5 is a high voltage, micropower low dropout linear regulator capable of supplying 50mA output current with a dropout voltage of 300mV. Designed for use in battery-powered or high voltage systems, the low quiescent current (30μA operating and 1μA in shutdown) makes the LT3010 an ideal choice. Quiescent current is also well controlled in dropout. Other features of the LT3010 include the ability to operate with very small output capacitors. The regulators are stable with only 1μF on the output while most older devices re- quire between 10μF and 100μF for stability. Small ceramic capacitors can be used without the necessary addition of ESR as is common with other regulators. Internal protec- tion circuitry includes reverse-battery protection, current limiting, thermal limiting and reverse current protection. The device is available in a fi xed output voltage of 5V and as an adjustable device with a 1.275V reference voltage. The LT3010 regulator is available in the 8-lead MSOP pack- age with an exposed pad for enhanced thermal handling capability.
