(very low dropout) linear regulator which operates from input voltages as low as 1.7V. The device is capable of supplying 300mA of output current with a typical dropout voltage of only 45mV. To allow operation at low input voltages the LTC3035 includes a charge pump generator that provides the necessary bias voltage for the internal LDO circuitry. Output current comes directly from the input supply for high efficiency regulation. The charge pump bias generator requires only a 0.1μF flying capacitor and a 1μF bypass capacitor for operation. The low 0.4V internal reference voltage allows the LTC3035 to be programmed to much lower output voltages than commonly available in LDOs. The output voltage is programmed via two tiny SMD resistors. The LTC3035’s low quiescent current makes it an ideal choice for use in battery-powered systems.Other features include high output voltage accuracy, excellent transient response, stability with ultralow ESR ceramic capacitors as small as 1μF, short-circuit and thermal overload protection, output current limiting and reverse output current protection. The LTC3035 is available in a tiny, low profile (3mm × 2mm × 0.75mm) 8-lead DFN package.
