A LOW DROPOUT LINEAR REGULATOR Description Features The is a series of low dropout positive voltage regulators with a maximum dropout of.5v at A of load current. The series features on-chip thermal shutdown. It also includes a bandgap reference and a current limiting circuit. The is available in.5v,.8v,.5v,.v, 5.V and adjustable versions. The fixed versions integrate the adjust resistors. The adjustable version can set the output voltage with two external resistors. The series is available in standard packages of TO6, TO6-, TO5- (), TO5- (4) and TO5- (5). Applications Low Dropout Voltage: Typical.V at A Current Limiting and Thermal Protection Output Current: A Current Limit: 4.5A Operating Junction Temperature: to +5 C Compatible with Low ESR Ceramic Capacitor Line Regulation:.5% (Typ) Load Regulation:.% (Typ) Lead-Free Packages: TO6, TO6- Totally Lead-Free; RoHS Compliant (Notes & ) Lead-Free Packages, Available in Green Molding Compound: TO6, TO6-, TO5- (), TO5- (4), TO5- (5) Totally Lead-Free & Fully RoHS Compliant (Notes & ) Halogen and Antimony Free.

Stresses greater than those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to Absolute Maximum Ratings for extended periods may affect device reliability. 5. Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the device outside of its operating ratings. The maximum allowable power dissipation is a function of the maximum junction temperature, T J(max), the junction-toambient thermal resistance, θ JA, and the ambient temperature, T A. The maximum allowable power dissipation at any ambient temperature is calculated using: P D(max) = (T J(max)-T A)/θ JA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. of
