DESCRIPTIO  
FEATURES  
The LTC®3035 is a micropower, VLDO™ (very low drop-  
out)linearregulatorwhichoperatesfrominputvoltagesas  
low as 1.7V. The device is capable of supplying 300mA of  
output current with a typical dropout voltage of only  
45mV.ToallowoperationatlowinputvoltagestheLTC3035  
includes a charge pump generator that provides the nec-  
essary 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, ex-  
cellent 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 avail-  
able in a tiny, low profile (3mm × 2mm × 0.75mm) 8-lead  
DFN package.
