The device is capable of supplying 300m A of output current with a typical dropout voltage of only 45m V. 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 es 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 monly 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. , LTC and LT are registered trademarks of Linear Technology Corporation. VLDO is a trademark of Linear...
