Description
uP7701 3A Ultra Low Dropout Linear Regulator General Description Features The uP7701 is a 3A ultra low dropout linear regulator specifically designed for motherboard,notebook and graphic card applications. This device works with dual supplies, a control input for the control circuitry and a power input as low as 1.0V for providing current to output. The uP7701 delivers high-current and ultra-low-drop output voltage as low as 0.8V for applications where VOUT is very close to VIN. The uP7701 features comprehensive control and protection functions: a power on reset (POR) circuit for monitoring both control and power inputs for proper operation; an EN input for enabling or disabling the device, a power OK with time delay for indicating the output voltage status, a foldback current limit function, and a thermal shutdown function. The uP7701 is available in PSOP-8 package with very low thermal resistance. Applications † Desktop PCs, Notebooks, and Workstations † Graphic Cards † Low Voltage Logic Supplies † Microprocessor and Chipset Supplies † Split Plane Microprocessor Supplies † Advanced Graphics Cards Supplies † SoundCards and Auxiliary Power Supplies † SMPS Post Regulators † Works with 1.0V~5.5V VIN „ Adjustable Output Voltage, Down to 0.8V „ 1.5% Initial Accuracy „ Excellent Line and Load Regulation † 3A Guaranteed Output Current „ 300mV @ 3A Dropout Voltage † Very Low On-Resistance „ 100mΩ typical † VOUT Pull Low Resistance when Disabled † Low Reverse Leakage (Output to ...
