Technical Attributes
Description ZLDO1117 is a low dropout positive adjustable or fixed-mode regulator with 1A output current capability. The ZLDO1117 has a 2% tolerance across the industrial temperature range and is guaranteed to have lower than 1.2V dropout at full load current making it ideal to provide well-regulated outputs of 1.2V to 5.0V with input supply voltages up to 18V. The ZLDO1117 is ideally suited to provide well-regulated supplies for low voltage IC applications such as high-speed bus termination and low current 3.3V logic supply across the whole industrial temperature range.Features • 1.2V Maximum Dropout at Full Load Current • 2% Tolerance Over Temperature, Line and Load Variations • Fast Transient Response • Output Current Limiting • Built-in Thermal Shutdown • Good Noise Rejection • Suitable for use with MLCC Capacitors • Qualified to AEC-Q100 Grade 2 (see ‘Ordering Information’) • PPAP capable (Note 4) • -40 to +125°C Junction Temperature Range • Available in TO252 and SOT223 with “Green” Molding Compound(No Br, Sb) Lead-Free Finish; RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. “Green” Device (Note 3)
