1 / 6 page POWER MANAGEMENT 1 www.semtech.com EZ1117/EZ1117A 0.8 & 1.0 AMP Positive Voltage Regulators Description Description Low dropout performance, 1.2V max. for EZ1117 1.3V max. for EZ1117A Full current rating over line and temperature Fast transient Response ±2% total output regulation over line, load and temperature Adjust pin current max 90μA over temperature Fixed/adjustable output voltage Line regulation 0.2% max. Load regulation 0.4% max. SOT-223 and TO-263 packages May 23, 2006 The EZ1117 series of high performance positive voltage regulators are designed for use in applications requiring low dropout performance at full rated current. Additionally, the EZ1117 series provides excellent regulation over variations in line, load and temperature. Outstanding features include low dropout performance at rated current, fast transient response, internal current limiting and thermal shutdown protection of the output device. The EZ1117 series of three terminal regulators offer fixed and adjustable voltage options available in the space saving SOT-223 and TO-263 packages.
