It takes an input as low as 0.8 V and delivers an adjustable output up to 6 V, with a 500 mA switch current limit. ## What the ratings mean for the BOM The 0.8 V minimum input lets you run this off a nearly dead alkaline cell. The 500 mA switch current is the peak the internal switch can handle. ## Package and footprint Standard 8-SOIC package — 0.154\" wide, 3.90 mm body width. Hand-solderable with a fine tip and steady hand. Pin 1 orientation is marked by a dot on the package top. The tube delivery means the parts slide out one by one; store them in conductive foam or ESD bag after opening. ## Lifecycle and sourcing RoHS3 compliant. Sourced through independent distribution; quoted to order against an RFQ.","metaTitle":"MAX857ESA+ Boost Regulator, 500mA Switch, 8-SOIC","metaDescription":"MAX857ESA+ step-up boost regulator from Analog Devices. 0.8V to 6V input, adjustable output, 500mA switch, 500kHz, -40°C to 85°C, 8-SOIC.
