The PAM3101 series of positive voltage linear regulators feature low quiescent current (65μA typ.) and low dropout voltage, making them ideal for battery powered applications. Their high PSRR make them useful in applications where AC noise on the input power supply must be suppressed. Space-saving TSOT25, SOT-23, SOT-89, SC70 and DFN1.6x1.6-6L packages are attractive for portable and handheld applications. They have both thermal shutdown and current limit features to prevernt device failure from extreme operating conditions. They are stable with an output capacitor of 2.2μF or greater.


  • Low Dropout Voltage: 180mV@300mA (VO = 3.3V)
  • Output Voltage Accuracy within ±2%
  • Supply Voltage Range: 2.5V to 5.5V
  • Quiescent Current: 65μA typ.
