The MC33167TG4RE is a switching regulator from Motorola Solutions, specifically designed for use in automotive and industrial applications. This regulator, part of the MC33167 series, is a high-performance, monolithic, integrated, low-noise low-dropout linear voltage regulator.
The MC33167TG4RE switching regulator features a fixed 2:1 input/output ratio, making it ideal for applications where a step-down voltage conversion is required. It operates with an input voltage range of 10V to 36V and provides a regulated output voltage of 5V. The regulator is capable of delivering a maximum continuous output current of 2A, making it suitable for powering a variety of low-power electronic devices.
One of the standout features of the MC33167TG4RE is its low-noise performance. The regulator's noise level is less than 15mVp-p, ensuring clean and stable power delivery to the load. Additionally, it features a shutdown mode that reduces the quiescent current to less than 100 A, further reducing power consumption when the output is not in use.
The MC33167TG4RE is also designed for robustness and reliability. It features a wide operating temperature range of -40 C to 125 C, making it suitable for use in a variety of environmental conditions. The regulator is also protected against short-circuit and over-temperature conditions, ensuring its long-term reliability in the field.
In summary, the MC33167TG4RE is a high-performance, low-noise, and reliable switching regulator from Motorola Solutions. Its fixed 2:1 input/output ratio, low-noise performance, and robust design make it an excellent choice for use in automotive and industrial applications where a step-down voltage conversion is required.
The MC33167TG4RE and TO220 versions of the MC33167 switching regulator are both manufactured by Motorola, but they have some key differences that could influence your decision to buy one over the other.
Pros of the MC33167TG4RE:1. Small Size: The MC33167TG4RE is a small-scale package, which makes it easy to integrate into compact designs.
2. High Output Current: This version can deliver up to 2.5A of output current, making it suitable for powering high-current loads.
3. Wide Input Voltage Range: The MC33167TG4RE can operate from an input voltage as low as 2.5V and as high as 40V, making it versatile for various power supply applications.
Pros of the TO220:1. Large Heat Sink: The TO220 package provides a large heat sink area, which allows for improved thermal management and reliability in high-power applications.
2. Easy Mounting: The TO220 package is easy to mount on a PCB or a heatsink, and it can be easily handled due to its large size.
3. Lower Cost: The TO220 package is often cheaper than the smaller MC33167TG4RE package due to its larger production volume.
Cons of the MC33167TG4RE:1. Limited Heat Sink Area: The small size of the MC33167TG4RE package may limit its ability to handle high heat loads without a separate heat sink.
2. Lower Power Handling: The smaller package may not be able to deliver as much power as the larger TO220 package.
Cons of the TO220:1. Larger Size: The TO220 package is larger than the MC33167TG4RE, which may require more space on your PCB.
2. Lower Output Current: The TO220 package may not be able to deliver as much output current as the MC33167TG4RE due to its larger heat sink area.
In conclusion, the choice between the MC33167TG4RE and TO220 depends on your specific application requirements. If you need a small, high-power regulator that can handle high input voltages, the MC33167TG4RE may be the better option. However, if you need to handle high heat loads or require a lower-cost solution, the TO220 package could be more suitable. It is important to carefully evaluate your power supply requirements to make an informed decision.
