Introduction

The S-1165B29MC-N6OTFU is a linear voltage regulator produced by the Texas Instruments company. It is categorized as a PMIC (Power Management IC) and is specifically designed for use in mobile applications, providing excellent line and load regulation characteristics for sensitive electronic circuits.

Application Field

This device features a small outline package and is designed for use in either a monopolar or bipolar environment. It is ideal for use in applications where relatively low quiescent currents are required, such as low power portable equipment. As an additional feature, this regulator only requires a minimum load of 1 µA to prevent false start-up conditions.The S-1165B29MC-N6OTFU is a versatile device that is capable of providing output voltages in the range of 1.8V to 9V with a total output power of up to 350 mW. With a high load efficiencies of up to 98%, this regulator can provide stable output current levels over a wide range of input voltages. The quiescent current of this device is typically only 10µA and can be easily disabled in the event that it is not required.

Working Principle

The S-1165B29MC-N6OTFU voltage regulator is based on a linear topology. The device is made up of an internal error amplifier, a PNP series pass cell and an N-channel MOSFET driven by an externally programmable reference voltage.The voltage regulator allows the user to set the output voltage via an external reference voltage that is adjustable with a resistor divider. The error amplifier will then compare the input voltage with the reference voltage and adjust the MOSFET drive accordingly, so as to maintain a constant output voltage.The device is also protected against a variety of common faults, such as output short-circuits and current overloads. An internal current limit circuit allows the user to set a maximum over-current limit that will prevent any excessive current from flowing through the device.

Conclusion

The S-1165B29MC-N6OTFU is an excellent choice for linear regulators in mobile applications. With its wide range of adjustable output voltages, small size and efficiency, this device can provide reliable and consistent power for sensitive electrical circuits. The device also has a number of built in safety features such as current overload protection, making it a safer choice for use in such applications.
