PMIC - Voltage Regulators - Linear

The LT3032IDE#PBF is a high performance 4.5V to 16V Low Noise and Low Dropout Linear Regulator from the company Linear Technology, ideally suited for circuitry requiring a very low output noise, or in applications that require extremely high accuracy over a wide temperature range. It features low IOUT, Accurate Voltage Droop and adjustable current limit. The 3-Terminal device has typical 0.02% line regulation, and shuts down when the current limit is exceeded for protection in the event of an output short circuit.

Application Fields

The LT3032IDE#PBF is suitable for many applications including: 1) Automotive Electronics, such as tachometers, sensors, actuators, and other motor control devices; 2) Battery Charging and Battery Management System (BMS) Applications; 3) Portable Instruments, including handheld devices, medical equipment, and portable radios; 4) Instrumentation and Control Applications; 5) Handheld radios, cellular phones, and portable electronic devices.

Working Principle

The LT3032IDE#PBF consists of a linear regulator, an output voltage divider, an input capacitor, and an output capacitor. The input and output capacitors are used for stability and noise reduction, respectively. The output voltage is set by the resistor divider, which adjusts the reference voltage applied to the regulator. The regulator senses the difference between its reference voltage and the actual source voltage, and adjusts its output to maintain this difference. The feedback loop of the linear regulator controls the output voltage as a function of input voltage, temperature, and load current. This accurately maintained output voltage is then provided to the load connected to the output of the LT3032IDE#PBF.

The LT3032IDE#PBF\'s large operating temperature range (-40°C to 125°C) makes it ideal for automotive, instrumentation, and industrial applications. Low dropout voltage, high accuracy and very low output noise are additional benefits for these applications. The excellent temperature stability of the LT3032IDE#PBF allows for precision regulation in the most challenging applications.

Conclusion

The LT3032IDE#PBF is a versatile and reliable three-terminal linear regulator, ideal for automotive, industrial, and instrumentation applications requiring low dropout voltage, high accuracy, and very low output noise. It operates over a wide temperature range, is highly accurate, and offers excellent temperature stability. It is a reliable and cost-efficient solution for many applications.
