LT3013 is a high voltage, micropower low dropout linear regulator. The device is capable of supplying 250mA of output current with a dropout voltage of 400mV. Designed for use in battery-powered or high voltage systems, the low quiescent current (65μA operating and 1μA in shutdown) makes the LT3013 an ideal choice. Quiescent current is also well controlled in dropout. Other features of the LT3013 include a PWRGD flag to indicate output regulation. The delay between regulated output level and flag indication is programmable with a single capacitor. The LT3013 also has the ability to operate with very small output capacitors. The regulator is stable with only 3.3μF on the output while most older devices require between 10μF and 100μF for stability. Small ceramic capacitors can be used without any need for series resistance (ESR) as is common with other regulators. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting and reverse current protection. The device is available with an adjustable output with a 1.24V reference voltage. The LT3013 regulator is available in the thermally enhanced 16-lead TSSOP and the low profile (0.75mm), 12-pin (4mm × 3mm) DFN package, both providing excellent thermal characteristics.
The LT3013 linear regulator is designed for battery‑powered and high‑voltage systems, providing up to 250 mA of output current with a low quiescent draw. It supports a wide input voltage range of 4 V to 80 V and features an adjustable output from 1.24 V to 60 V, making it suitable for telecom, automotive, and other low‑current high‑voltage applications.
Key features include a low dropout voltage of 400 mV at full load, reverse‑battery protection, thermal limiting, and the ability to operate with very small output capacitors. The device is offered in thermally enhanced 16‑lead TSSOP and 12‑pin DFN (4 mm × 3 mm) packages for flexible board‑level integration.
