Features

* o Fixed Outputs: 3.3V (MAX687/MAX688) 3.0V (MAX689) o Directly Drives External PNP Transistor o 10mA Min Base-Current Drive for >1A Output o Low Dropout Voltage: 100mV Dropout at 650mA Output (FZT749) 40mV Dropout at 200mA Output (FZT749) 0.8V Dropout at 4A Output o Power-Fail Output Monitors the Ou

Applications

* include portable telephones and other battery-powered equipment where the power supply must be disabled when the battery voltage is low. The MAX688 and MAX689 do not have an automatic shutdown function, and are identical except for their output voltages. Each device has an active-low shutdown-contro
