1 3-TERMINAL A POSITIE OLTAGE REGULATOR FEATURES Output Current Up to 100 No External Components Internal Thermal Overload Protection Internal Short-Circuit Limiting Output oltage of 5, 6, 8, 9, 10, 12, 15, 18 and 24 Moisture Sensitivity Level 3 PKG SOT-89 PKG DESCRIPSION This series of fixed-voltage monolithic integrated-circuit voltage regulators is designed for a wide range of applications. These applications include on-card regulation for elimination of noise and distribution problems associated with single-point regulation. In addition, they can be used with power-pass elements to make high current voltage regulators. Each of these regulators can deliver up to 100 of output current. The internal limiting and thermal shutdown features of these regulators make them essentially immune to overload. Current limiting is include to limit the peak output current(250 ~ 300) to a safe value. When used as a replacement for a zener diode-resistor combination, an effective improvement in output impedance can be obtained together with lower-bias current.

10 3-TERMINAL A POSITIE OLTAGE REGULATOR Note 1. Pulse testing techniques are used to maintain the junction temperature as close to the ambient temperature as possible. Thermal effects must be taken into account separately. All characteristics are measured with a 0.33uF capacitor across the input and a uf capacitor across the output. Note 2. This specification applies only for DC power dissipation permitted by absolute maximum ratings. Oct Rev HTC
