TS9007 series

The TS9007 series is one kind of 300mA ultra-low-noise LDO especially which 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.

It can be used in palmtops,pDA and notebook computers;DSC,handset camera modules;PCMCIA cards,PC cameras;USB based portable devices (MPS, PMP) and GSM/GPRS/3G RF transceiver modules.Also the TS9007 series has some important features such as:(1)450mV dropout at 300mA load (3.3V);(2)low quiescent current: 90A;(3)output voltage ±2%;(4)internal current limit and thermal shutdown;(5)power saving shutdown mode (<1uA);(6)only need input and output capacitors;(7)build-In internal soft-start;(8)output short-circuit current limit protection.

The absolute maximum rating of the TS9007 series can be summarized as:(1)supply voltage:-0.3 to +7 V;(2)input supply voltage (recommended):+2 to +6 V;(3)output short-circuit duration:infinite;(4)junction temperature range:+150°C;(5)storage temperature range:-65 to +150°C.If you want to know more information such as the electrical characteristics about this part,please download the datasheet in www.seekic.com and www.chinaicmart.com .
