GENERAL DESCRIPTION
An active-low, open-drain reset output remains asserted for at least 2.2ms (MAX1963) or 70ms (MAX1976) after the output voltage reaches regulation. An internal PMOS pass transistor allows the low supply current to remain independent of load and dropout voltage, making these devices ideal for portable battery-powered equipment such as personal digital assistants (PDAs), cell phones, cordless phones, and notebook computers. Other features include logic-controlled shutdown, short-circuit protection, and thermal-overload protection. o Low 1.62V Minimum Input Voltage o Guaranteed 300mA Output Current o ±1.5% Accuracy Over Load/Line/Temp o Low 100mV Dropout at 300mA Load o 2.2ms (MAX1963) or 70ms (MAX1976) RESET Output Flag o Supply Current Independent of Load and Dropout Voltage o Logic-Controlled Shutdown o Thermal-Overload and Short-Circuit Protection o Preset Output Voltages (0.75V to 3.0V) o Tiny 6-Pin Thin SOT23 Package (<1.1mm High) o Thin 6-Pin TDFN Package (<0.8m...
