Dual, 300mA Low-Dropout Linear Regulators Features Two Low-Dropout-Voltage Regulators 300mA Output Current for Each LDO Independent Enable Control Dropout Voltage is 100mV@ 100mA Load Over-Temperature Protection and Short-Circuit Protection 1.2V to 3.3V Factory-Preset Output Max. Supply Current in Shutdown Mode < 1µA Small Ceramic Output Capacitors 400 Ω V OUT Discharge Resistance in Shutdown Applications Notebook Computers Cellular Phones PDAs Digital still Camera and Video Recorders Hand-Held Devices Bar Code Scanners General Description The G9294 is a dual, low supply current, low dropout linear regulator that comes in a space saving TSOT-23-6 & TDFN1.6X1.6-6 and TDFN2X2-8 pack- age. The supply current at no-load is 60µA. In the shutdown mode, the maximum supply current is less than 1µA. Output voltage range of the G9294 is from 1.2V to 3.3V. The over-current protection limit is set at 500mA typical. An over-temperature protection circuit is built-in in the G9294 to prevent thermal overload. These power saving features make the G9294 ideal for use in the battery-powered applications such as notebook computers, cellular phones, and PDA’s. These devices feature a shutdown function and are of- fered in active low with auto discharge. The G9294 comes in a space saving TSOT-23-6, TDFN1.6X1.6-6 and TDFN2X2-8 package.
