LM137QML
3-Terminal Adjustable Negative Regulator
制造商:TI
产品信息
描述 The LM137 are adjustable 3-terminal negative voltage regulators capable of supplying in excess of 1.5 A over an output voltage range of −37 V to −1.2 V. These regulators are exceptionally easy to apply, requiring only 2 external resistors to set the output voltage and 1 output capacitor for frequency compensation. The circuit design has been optimized for excellent regulation and low thermal transients. Further, the LM137 series features internal current limiting, thermal shutdown and safe-area compensation, making them virtually blowout-proof against overloads.The LM137 serve a wide variety of applications including local on-card regulation, programmable-output voltage regulation or precision current regulation. The LM137 are ideal complements to the LM117 adjustable positive regulators.特性SMD 5962-99517 Available TID Qualified to 30 krad(Si) Output Voltage Adjustable from −37 V to −1.2 V 1.5A Output Current Guaranteed, −55°C to +150°C Line Regulation Typically 0.01%/V Load Regulation Typically 0.3% Excellent Thermal Regulation, 0.002%/W 77 dB Ripple Rejection Excellent Rejection of Thermal Transients 50 ppm/°C Temperature Coefficient Temperature-independent Current Limit Internal Thermal Overload Protection Standard 3-lead Transistor Package Output is Short Circuit Protected

在JavaScript中动态的创建QML对象在实际QML应用开发中,我们可以在JavaScript中动态的创建QML对象。这样做可以延迟对象的实例化,当我们在需要创建对象的时候才在JavaScript代码中创建,则可以缩短应用程序的启动时间,还可以动态创建可视对象,有助于提高应用程序性能。
