Microchip LR12LG-G

LR12LG-G General Description

With its ability to handle high voltage inputs and deliver low output currents, the LR12LG-G stands out as a versatile and reliable linear regulator suitable for a variety of applications. The regulator boasts an impressive input voltage range of 13.2 - 100V, providing ample flexibility to accommodate different voltage requirements. Its adjustable output voltage, ranging from 1.20 - 88V, can be easily configured using external resistors R1 and R2, offering precise customization options. The LR12 also includes current and temperature limiting features to ensure safe and efficient operation. It has a maximum output current limit of 100mA and a temperature limit of 125°C, effectively protecting against potential overloading and overheating. Additionally, for SMPS start-up circuit applications, the LR12 features a built-in shutdown function to prevent damage from external voltage inputs exceeding the output voltage. To maintain stability and reliability, a bypass capacitor of 100nF or larger, along with a minimum DC output current of 500µA, are essential requirements
