TAIWAN SEMICONDUCTOR TS1117B Series Taiwan Semiconductor 1A Low Dropout Positive Voltage Regulator DESCRIPTION TS1117B are high performance positive voltage regulators are designed for use in applications requiring low dropout performance at full rated current. Additionally; TS1117B 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. TS1117B are three terminal regulators with fixed and adjustable voltage options available in popular packages. FEATURES • Low Dropout Performance 1.5V max. • Fast T ransient Response • Built-in thermal shutdown • Output Current Limit • Line Regulation Typical 0.2% • Load Regulation Typical 0.05% • Low-ESR Ceramic Capacitor (MLCC) required for Stability. • Good Ripple Rejection • Compliant to RoHS Directive 2011/65/EU and WEEE 2002/96/EC • Halogen-free according to IEC 61249-2-21 APPLICATION • PC peripheral • Communication • Consumer equipment HALOGEN FREE Pb-Free COMPLIANT Notes: MSL 3 (Moisture Sensitivity Level) per J-STD-020 TYPICAL APPLICATION CIRCUIT Fixed output voltage version

TAIWAN SEMICONDUCTOR TS1117B SeriesTaiwan Semiconductor ABSOLUTE MAXIMUM RATINGS Notes: R©ja is the sum of the junction-to-case and case-to-ambient thermal resistances. The case thermal reference is defined at the solder mounting surface of the drain pins. R©ja is guaranteed by design while R©ca is determined by the user’s board design. R©ja shown below for single device operation on FR-4 PCB in still air. 1. See thermal regulation specification for changes in output voltage due to heating effects. Line and load regulation are measured at a constant junction temperature by low duty cycle pulse...
