Supply Current in Shutdown Mode < 1µA Stable with Low Cost Ceramic Capacitors EN with Internal Pull-Low Resistance Applications Notebook Computers Cellular Phones PDAs Digital still Camera and Video Recorders Hand-Held Devices Bar Code Scanners General Description The G909 is a low supply current, low dropout linear regulator that comes in a space saving SOT-23-5, TSOT-23-5, SC-70-4 (SC-82 / SOT-343), SC-70-5 (SOT-353) and TDFN2X2-8 package. The supply current at no-load is 100µA. In the shutdown mode, the maxi- mum supply current is less than 1µA. The over-current protection limit is set at 240mA typical. An overtem- perature protection circuit is built-in in the G909 to prevent thermal overload. These power saving fea- tures make the G909 ideal for use in the bat- tery-powered applications such as notebook com- puters, cellular phones, and PDA’s. These devices feature an enable function and are of- fered in active high with auto discharge. The G909 is specifically designed to employ ceramic output ca- pacitors as low as 0.47µF.The G909 comes in a space saving SOT-23-5, TSOT-23-5, SC-70-4 (SC-82 / SOT-343), SC-70-5 (SOT-353) and TDFN2X2-8 package.
