General Description
The TS9007 series is 300mA ultra-low-noise LDO 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 15uVrms 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.
