G9052 Global Mixed-mode Technology Inc. Dual, 300mA Low-Dropout Linear Regulators Features General Description The G9052 is a dual, low supply current, low dropout linear regulator that comes in a space saving 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 430mA typical. An over-temperature protection circuit is built-in in the G9052 to prevent thermal overload. These power saving features make the G9052 ideal for use in the battery-powered applications such as notebook computers, cellular phones, and PDA’s. Two Low-Dropout-Voltage Regulators Pin-Programmable Output Voltages 300mA Output Current for Each LDO Independent Enable Control Dropout Voltage is 90mV@ 100mA Load Over-Temperature Protection and Short-Circuit Protection Max. Supply Current in Shutdown Mode < 1µA Small Ceramic Output Capacitors Applications The G9052 have two logic inputs that select one of nine preset output-voltage combinations, eliminating external 1% resistors. The G9052 configures output voltages at VOUT1 and VOUT2 based on the state of P1 and P2 at power-on. Subsequent changes to P1 and P2 do not change the output voltages unless the supply power is cycled, or all EN inputs are simultaneously driven low to shut down the device. These devices feature a shutdown function and are offered in active low with auto discharge. The G9052 comes in a space saving TDFN2X2-8 package.
