I am looking for an LDO with Min Vout = 0.8V to Max Vout = 1.2V. Vin is adjustable (always greater than 2V). Iload expected is about 100mA at Vout = 0.8V. It is for an application running at ~100MHz, so PSRR should be around 20-25dB at this frequency (not a strict requirement). We don't really care about the power consumption of the LDO, capped or capless LDO.
So is LTC3035 the best match for our specs..??
LTC3035 should be ok in your application. But because there is enough headroom between Vout and Vin, you may not necessarily need the charge pump feature of this device. I searched in analog.com and found these parts to be also ok. See link below.
