1 TS m Low ropout Positive Voltage Regulator TO-263 Low ropout Voltage 1.3V max. eneral escription Pin assignment: 1. round / dj 2. Output 3. nput The TS1117 Series are high performance positive voltage regulators are designed for use in applications requiring low dropout performance at full rated current, dditionally, the PJ1117 Series provides excellent regulation over variations due to changes 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 TS1117 Series are three terminal regulators with fixed and adjustable voltage options available in popular packages. This series is offered in 3-pin TO-263, TO-220, TO-252 and SOT-223 package. eatures Low dropout performance 1.3V max. ull current rating over line and temperature. ast transient response ±2%Total output regulation over line, load and temperature djust pin current max 90µ over temperature Line regulation typical 0.015%.

Line and load regulation are measured at a constant junction temperature by low duty cycle pulse testing. Load regulation is measured at the output lead = 1/18 from the package. Note 2: Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by the input / output voltage difference and the output current. uaranteed maximum power dissipation will not be available over the full input / output voltage range. Note 3: Quiescent current is defined as the minimum output current required to maintain the regulation. TS /12 rev.
