Review STMICROELECTRONICS Qty 100-stmicro-ld1117s Dropout Voltage Regulators 3.3v 0.8a Positive
The 100-STMicroelectronics LD1117S is a low dropout voltage regulator that is ideal for applications requiring a stable 3.3V output with a maximum current of 0.8A. This regulator is manufactured by STMicroelectronics, a renowned company known for its high-quality semiconductor products.
The LD1117S is a linear regulator, which means it generates its output voltage through the dissipation of power. It has a very low dropout voltage of 200mV at no load, making it suitable for applications where a minimal voltage drop is essential. This feature also allows the regulator to maintain its output voltage even when the input voltage dips slightly, ensuring a stable supply to the load.
The LD1117S has a wide input voltage range of 2.7V to 36V, making it versatile in various input voltage conditions. It is a single-output regulator, providing a regulated 3.3V output. The regulator is compact in size, measuring 3mm x 3mm, making it suitable for space-constrained applications.
The LD1117S is designed with a high level of protection. It features internal over-temperature protection, which shuts down the regulator when the junction temperature reaches 125 C to prevent damage. It also has a thermal shutdown feature, which turns off the regulator when the input current exceeds the maximum rating, protecting the regulator and the connected load from overheating.
The LD1117S has a high input/output voltage compatibility, allowing it to work with input voltages higher than the output voltage. This feature ensures that the regulator operates efficiently even when the input voltage is significantly higher than the required output voltage.
In conclusion, the 100-STMicroelectronics LD1117S is a high-performance, low dropout voltage regulator that provides a stable 3.3V output with a maximum current of 0.8A. Its low dropout voltage, wide input voltage range, and high level of protection make it an excellent choice for various applications requiring a stable power supply.
The 100-STMicroelectronics LD1117S is a low dropout voltage regulator that provides a stable 3.3V output with a maximum current of 0.8A. Here are some pros and cons of using this regulator:
Pros:1. Low dropout voltage: The LD1117S has a low dropout voltage of 2.4V, which means it can maintain a stable output voltage even when the input voltage is close to the output voltage. This makes it suitable for powering low-voltage devices.
2. Wide input voltage range: The regulator can operate with an input voltage ranging from 2.7V to 36V, making it versatile for various power sources.
3. High efficiency: The LD1117S has a high efficiency of up to 85% at light loads, which means it can convert a significant portion of the input power into output power, reducing heat dissipation.
4. Small size: The LD1117S is a small-sized regulator, making it easy to integrate into compact designs.
Cons:1. Limited current output: The LD1117S has a maximum current output of 0.8A, which may not be sufficient for powering high-current devices.
2. High noise level: The LD1117S has a high noise level, which may affect the performance of sensitive devices.
3. Limited temperature range: The LD1117S has a limited temperature range of -40 C to 125 C, which may not be suitable for high-temperature applications.
In conclusion, the 100-STMicroelectronics LD1117S is a suitable regulator for powering low-voltage devices with a wide input voltage range and high efficiency. However, its limited current output, high noise level, and limited temperature range may be limitations for some applications. If you require a higher current output or a wider temperature range, you may consider using a different regulator. Overall, the LD1117S is a reliable and cost-effective choice for low-power applications.
