It can be used to give a fixed +5 V output with no additional external components or can be adjusted from +1.3 V to +16 V using two external 400 resistors. Fixed or adjustable operation can be selected via the T = +50C A SET input. The low quiescent current (17 A) in conjunction with the standby or shutdown mode (0.2 A) makes this device especially suitable for battery powered systems. The dropout 300 GUARANTEED 300mA voltage when supplying 100 A is only 15 mV allowing opera- tion with minimal headroom thereby prolonging the useful bat- tery life. At higher output current levels the dropout remains 200 ADP3367 low increasing to just 150 mV when supplying 200 mA. A wide DISSIPATION LIMIT input voltage range from 2.5 V to 16.5 V is allowable. Addi- tional features include a dropout detector and a low supply/bat- 100 tery monitoring comparator. The dropout detector can be used STANDARD SO PACKAGE to signal loss of regulation while the low battery detector can be DISSIPATION LIMIT used to monitor the input supply voltage. 0 015105 The ADP3367 is a much improved pin-compatible replacement V V V IN OUT for the MAX667. Improvements include lower supply current, tighter voltage accuracy and superior line and load regulation. Load Current vs. Input-Output Differential Voltage Improved ESD protection (>6000 V) is achieved by advanced voltage clamping structures. The ADP3367 is specified over the ADIs proprietary Thermal Coastline leadframe used in ADP3367AR industrial temperature range 40C to +85C and is available in packaging, has 30% lower thermal resistance than the standard narrow surface mount (SOIC) packages. leadframes. This improvement in heat flow rate results in lower die temperature hence improves reliability.
