GENERAL DESCRIPTION
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.

FEATURES
    Maximum output current: 1 A
    Input voltage range: 2.5 V to 5.5 V
    Low shutdown current: <1 μA
    Low dropout voltage: 345 mV @ 1 A load
    Initial accuracy: ±1%
    Accuracy over line, load, and temperature: ±2.5%
    16 fixed output voltage options with soft start: 0.75 V to 3.3 V (ADP1706)
    16 fixed output voltage options with tracking 0.75 V to 3.3 V (ADP1707)
    Adjustable output voltage option: 0.8 V to 5.0 V (ADP1708)
    Stable with small 4.7 μF ceramic output capacitor
    Excellent load/line transient response
    Current limit and thermal overload protection
    Logic-controlled enable
    Available in an 8-lead, exposed paddle SOIC and 3 mm × 3 mm, 8-lead exposed paddle LFCSP
