LTC3035EDDB#TRMPBF

LTC3035 is a micropower, VLDO™ (very low dropout) linear regulator. This device is capable of supplying 300mA of output current with a typical dropout voltage of only 45mV. To allow operation at low input voltages, it includes a charge pump generator that provides the necessary bias voltage for the internal LDO circuitry. 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 device to be programmed to much lower output voltages than commonly available in LDOs. The output voltage is programmed via two tiny SMD resistors. It is widely used in application such as Li-Ion to 3.3V low dropout supplies, 2 × AA to 1.8V low dropout supplies, low power handheld devices, low voltage logic supplies, DSP power supplies, cellular phones, portable electronic equipment, handheld medical instruments, post regulator for switching supply noise rejection etc.
