Fixed 1.05 V rail — what this LDO is built for
The ADP1706ACPZ-1.05R7 is a single-output positive LDO from Analog Devices that delivers a fixed 1.05 V at up to 1 A. Enable and Soft Start are on-chip, so you can sequence the rail and limit inrush on power-up.
Dropout headroom and input range
Maximum input is 5.5 V. The dropout voltage is 0.6 V at 1 A.
Temperature grade and where it runs
Rated for junction temperature from -40°C to 125°C, so it's suited for industrial enclosures, outdoor telecom cabinets, and under-hood automotive modules — not just benchtop gear. The 8-LFCSP (3x3) package with exposed pad helps pull heat into the PCB copper. Quiescent current is 390 µA typical, supply current max is 1.55 mA — reasonable for always-on rails in battery-backed systems.
Protection and control
Over-current and over-temperature protection are built in. The Enable pin lets you gate the output for sequencing; Soft Start reduces the output ramp rate.
Lifecycle and sourcing
Analog Devices lists this part as Active and ROHS3 compliant.
