G909 Global Mixed-mode Technology Inc. 150mA Low-Dropout Linear Regulators Features 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 maximum supply current is less than 1µA. The over-current protection limit is set at 240mA typical. An overtemperature protection circuit is built-in in the G909 to prevent thermal overload. These power saving features make the G909 ideal for use in the battery-powered applications such as notebook computers, cellular phones, and PDA’s. Low, 100µA No-Load Supply Current Guaranteed 150mA Output Current Dropout Voltage is 210mV @ 150mA Load Over-Temperature Protection and Short-Circuit Protection Max. 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 These devices feature an enable function and are offered in active high with auto discharge. The G909 is specifically designed to employ ceramic output capacitors 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.
