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.
The LT3010 family is a high‑voltage micropower LDO designed for battery‑powered and telecom applications. It delivers up to 50 mA with a very low quiescent current and can operate from 3 V to 80 V input. The fixed‑output version (LT3010‑5) provides a regulated 5 V output, while the adjustable version (LT3010) can be set from 1.275 V to 60 V.
Key features include a 300 mV dropout voltage, 30 pA typical quiescent current (1 µA in shutdown), reverse‑battery protection, and stability with as little as 1 pF output capacitance. The device is supplied in an 8‑lead MSOP package with an exposed pad for enhanced thermal handling.
