The ADP3367ARZ is a Low Dropout Linear Voltage Regulator that can supply up to 300mA output current. It can be used to give a fixed +5V output with no additional external components or can be adjusted from +1.3 to +16V using two external resistors. Fixed or adjustable operation can be selected via the SET input. The low quiescent current (17μA) in conjunction with the standby or shutdown mode (0.2μA) makes this device especially suitable for battery powered systems. The dropout voltage when supplying 100μA is only 15mV allowing operation with minimal headroom thereby prolonging the useful battery life. At higher output current levels the dropout remains low increasing to just 150mV when supplying 200mA. Additional features include a dropout detector and a low supply/battery monitoring comparator. The dropout detector can be used to signal loss of regulation while the low battery detector can be used to monitor the input supply voltage.
