Product Details
The ADP3367 is a low-dropout precision voltage regulator that can supply up to 300 mA output current. 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 resistors. Fixed or adjustable operation can be selected via the SET input. The low quiescent current (17 µA) in conjunction with the standby or shutdown mode (0.2 µA) makes this device especially suitable for battery powered systems. The dropout voltage when supplying 100 µA is only 15 mV allowing operation with minimal headroom thereby prolonging the useful battery life. At higher output current levels the dropout remains low increasing to just 150 mV when supplying 200 mA. A wide input voltage range from 2.5 V to 16.5 V is allowable. 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.
The ADP3367 is a much improved pin-compatible replacement for the MAX667. Improvements include lower supply current, tighter voltage accuracy and superior line and load regulation. Improved ESD protection (>6000 V) is achieved by advanced voltage clamping structures. The ADP3367 is specified over the industrial temperature range -40°C to +85°C and is available in narrow surface mount (SOIC) packages.
ADI’s proprietary Thermal Coastline leadframe used in ADP3367AR packaging, has 30% lower thermal resistance than the standard leadframes. This improvement in heat flow rate results in lower die temperature hence improves reliability.
