Overview

Low 1.62V Minimum Input Voltage
Guaranteed 300mA Output Current
±2.5% Accuracy Over Load/Line/Temp
Low 100mV Dropout at 300mA Load
2.2ms (MAX1963A) or 70ms (MAX1976A) Active-Low RESET Output Flag
Supply Current Independent of Load and Dropout Voltage
Logic-Controlled Shutdown
Thermal-Overload and Short-Circuit Protection
Preset Output Voltages (0.75V to 3.0V)
Tiny 6-Pin Thin SOT23 Package (< 1.1mm High)
TDFN Package (< 0.8mm High)

The MAX1963A/MAX1976A low-dropout linear regulators operate from a +1.62V to +3.6V supply and deliver a guaranteed 300mA continuous load current with a low 100mV dropout. The high-accuracy (±0.5%) output voltage is preset to an internally trimmed voltage in the +0.75V to +3.0V range. An active-low, open-drain reset output remains asserted for at least 2.2ms (MAX1963A) or 70ms (MAX1976A) after the output voltage reaches regulation. These devices are offered in thin SOT23 and thin DFN packages. 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.
