G9291 Global Mixed-mode Technology Inc. 300mA Low-Dropout Linear Regulators Features General Description The G9291 is a low supply current, low dropout linear regulator that comes in a space saving TSOT-23-5, 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 430mA typical. An overtemperature protection circuit is built-in in the G9291 to prevent thermal overload. These power saving features make the G9291 ideal for use in the battery-powered applications such as notebook computers, cellular phones, and PDA’s. Low, 100µA No-Load Supply Current Guaranteed 300mA Output Current Dropout Voltage is 100mV @ 100mA Load Over-Temperature Protection and Short-Circuit Protection Max. Supply Current in Shutdown Mode < 1µA Stable with Low Cost Ceramic Capacitors Applications Notebook Computers Cellular Phones PDAs Digital still Camera and Video Recorders Hand-Held Devices Bar Code Scanners These devices feature a shutdown function and are offered in active low with auto discharge. The G9291 is specifically designed to employ ceramic output capacitors. The G9291 comes in a space saving TSOT-23-5 package. Ordering Information ORDER NUMBER MARKING VOLTAGE TEMP.
