It can be used in a wide variety of applications, such as mobile phones, digital cameras, medical instrumentation, voltage reference circuits, portable audio systems, and 12V automotive systems. Additionally, the device is lead-free, RoHS-compliant, and Halogen-free.

Working Principle

The LT3015ET-5#PBF is a monolithic low noise, low dropout linear regulator. It operates from a wide 4.5V to 36V input voltage range and is capable of delivering up to 100mA of regulated output current. The device features excellent transient load characteristics, making it suitable for use in a wide variety of applications.The LT3015ET-5#PBF employs an advanced constant-voltage regulation non-overlap drive technique to minimize cross-regulation and achieve high performance. The device also features a low quiescent current, wide voltage regulation range, and temperature tracking. The input voltage can exceed the output voltage by up to 100mV.The LT3015ET-5#PBF operates in three modes: two-phase dropout, dropout, and one-phase zero-current switching path. In two-phase dropout mode, the output voltage is regulated to within 1% accuracy with a specified dropout voltage and a minimum load current of 10mA. In dropout mode, the regulator provides current limiting and thermal protection. In one-phase zero-current switching path mode, the output voltage is regulated with a minimum load current of 10mA and no dropout voltage is required.The LT3015ET-5#PBF also features short-circuit protection and thermal protection, which protects the part from an excessive amount of current and prevents excessive heat buildup.

Conclusion

The LT3015ET-5#PBF is a low noise and low dropout linear regulator that is well suited for applications requiring high performance and flexibility, such as audio applications, medical instrumentation, communication systems and voltage reference circuits. The device operates in three modes, two-phase dropout, dropout, and one-phase zero-current switching path. It also has excellent line/load regulation characteristics and a wide 4.5V to 36V input voltage range. Additionally, it has short-circuit protection and thermal protection for added safety.
