Active production, 1A adjustable LDO in 10-uMAX-EP
The MAX8517EUB+ is an active-production linear regulator from Analog Devices, delivering 1A output current with an adjustable output voltage range from 0.5V to 3.4V. Maximum dropout is 0.2V at the full 1A load, meaning the input rail must stay at least 200 mV above the programmed output voltage across the load range to maintain regulation.
Protection and control features for rail sequencing
Integrated protection includes over-temperature shutdown, short-circuit current limiting, soft-start to reduce inrush, and under-voltage lockout (UVLO) that holds the output off until the input rail reaches the minimum threshold. An enable pin and a power-on-reset (POR) output allow sequencing of multiple rails: the POR asserts when the output is within regulation, providing a valid signal to downstream loads. Quiescent current is 320 µA typical, which sets the no-load power dissipation floor; in shutdown the enable pin reduces draw further, though the exact shutdown current is not specified in this record.
