LM3352MTC-2.5/NOPB

The LM3352MTC-2.5/NOPB is a precision voltage regulator in the DC DC switching regulators category from the PMIC family of components. This voltage regulator can provide an output voltage of 2.5 V, making it suitable for use in many general purpose applications. It is designed to ensure that the voltage output remains constant, even in the presence of varying temperatures and input voltages.

Features of LM3352MTC-2.5/NOPB

• Wide input voltage range (2.25V-6.0V)
• Output voltage: 2.5V
• Efficient operation
• Low input voltage operation
• High current capability
• Low Ripple
• Minimal external components
• Low noise operation

The LM3352MTC-2.5/NOPB operate with additional external components such as inductors, capacitors and resistors. The use of additional external components can improve its efficiency in case of higher current requirement. The regulator typically operates with a switching frequency of 1MHz but it can be set to about 9MHz for improved efficiency. It also provides for low ripple noise, which is a prerequisite for many high precision applications.

Working Principle

The LM3352MTC-2.5/NOPB voltage regulator utilizes Pulse Width Modulation (PWM) technology to regulate the voltage output. The PWM signal is produced by the internal comparator and driver circuit of the regulator which is continuously compared with a reference voltage. The reference voltage is determined by a series of resistors connected in a resistive divider network which produces a voltage proportional to the output voltage.

The output voltage of the regulator is then determined by the width of the pulses produced by the comparator and driver. The pulses are generally shorter when the input voltage is lower and the pulses get wider with an increase in the input voltage. The average output voltage is then proportional to the average of the pulse widths.

The LM3352MTC-2.5/NOPB voltage regulator also has an auto-compensation feature which means that it can automatically adjust the output voltage to compensate for changes in input voltage and temperature. This makes it especially suitable for use in applications where the supplies can experience a wide range of temperatures.

Applications

The LM3352MTC-2.5/NOPB voltage regulator can be used in a wide range of applications that require precision voltage regulation. It can be used in general purpose power supplies, batteries, automotive and charging systems, industrial systems, wireless communications, and multimedia applications. It is also suitable for use in digital audio and display systems.

The LM3352MTC-2.5/NOPB also has the ability to regulate up to a maximum current of 6.0A, making it suitable for a variety of high current applications. It is also able to operate with a wide input voltage range of 2.25V to 6.0V, making it suitable for use in environments with varying supplies. The low ripple output allows for high precision regulation of the voltage output and makes the LM3352MTC-2.5/NOPB a suitable choice for applications where low ripple is required.
