Product Details
●The ADP1706/ADP1707/ADP1708 are CMOS, low dropout linear regulators that operate from 2.5 V to 5.5 V and provide up to 1 A of output current. Using an advanced proprietary architecture, they provide high power supply rejection and achieve excellent line and load transient response with a small 4.7 μF ceramic output capacitor.
●The ADP1706/ADP1707 are available in 16 fixed output volt-age options. The ADP1708 is available in an adjustable version, which allows output voltages that range from 0.8 V to 5.0 V via an external divider. The ADP1706 allows an external soft start capacitor to be connected to program the start-up time; the ADP1707 and ADP1708 contain internal soft start capacitors that give a typical start-up time of 100 μs. The ADP1707 includes a tracking feature that allows the output to follow an external voltage rail or reference.
●The ADP1706/ADP1707/ADP1708 are available in an 8-lead, exposed paddle SOIC package and an 8-lead, 3 mm × 3 mm exposed paddle LFCSP, making them not only very compact solutions but also providing excellent thermal performance for applications requiring up to 1 A of output current in a small, low profile footprint.
