HT7130 Typical application circuit

1. Application Scenarios

1. Portable devices: Due to its low power consumption, the HT7130 is ideal for portable devices such as handheld game consoles, portable music players and personal digital assistants (PDAs). These devices require long battery life and stable voltage output, and the HT7130 is able to effectively meet these needs.

2. Battery-powered applications: In battery-powered systems, maintaining voltage stability is crucial. The HT7130 is able to provide a stable 3.0 volt output from the input power supply, keeping the output voltage stable even when the battery voltage fluctuates, which makes it ideal for applications in wireless communication devices, security systems, and more.

3. Low power system: For low power design, such as smoke alarms, environmental monitors, etc., the low static current characteristics of HT7130 are particularly important. These devices typically operate in standby mode with very low power requirements.

4. Medical equipment: Medical equipment such as portable blood glucose monitors and electronic thermometers require accurate and reliable power supplies, and the stable voltage output provided by the HT7130 ensures the measurement accuracy and reliability of these devices.

Second, parameter characteristics

1. Output voltage: The HT7130 provides a fixed 3.0V output voltage, which is a major feature of its design and is suitable for most electronic devices requiring low voltage.

2. Low voltage difference: the voltage difference of the regulator is as low as 1V, that is, the input voltage only needs to be 1V higher than the output voltage to work normally, which makes it able to provide a stable output when the battery voltage is below the ideal level.

3. Low static current: The static current of the HT7130 is very low, usually below 4 microamps, which is particularly important for extending battery life and reducing energy consumption.

4. Hot shutdown protection: The device has a hot shutdown function, which can automatically disconnect the output in the case of overheating to protect the circuit from damage.

5. Output current capability: HT7130 can provide a maximum output current of 50 MA, suitable for applications that do not require high current output.

To sum up, the HT7130 has found a wide range of applications in various electronic devices due to its high stability, low power consumption and user-friendly characteristics. It is designed to ensure that the equipment can maintain good performance under a variety of conditions, especially in environments with limited power conditions.
