The TS9007 ser ies is 300mA ultra-low-noise LD O especially designed for battery-power RF and wireless applications . The TS9007 regulator achieves a low 450mV dropout at 300mA load current of 3.3V output, ultra-low output voltage noise of 15uVr ms and PSRR of 57dB at 1KHz. The TS9007 regulators are also optimized to work with low- ESR and low cost ceramic capacitors reducing the amount of board space critical in hand-held devices . The TS9007 requires only 0.47uF output capacitor for stability with and load. The TS9007 consumes less than 1uA in shutdown mode.
