Circuits requiring steady 6v supply

7809 Voltage Regulator (Pack of 5) The LM7809 monolithic 3-terminal positive voltage regulators employ internal current-limiting, thermal shutdown and safe-area compensation, making them essentially indestructible. If adequate heat sinking is provided, they can deliver over 1.0A output current. They are intended as fixed voltage regulators in a wide range of applications including local (on-card) regulation for elimination of noise and distribution problems associated with single-point regulation. In addition to use as fixed voltage regulators, these devices can be used with external components to obtain adjustable output voltages and currents. Considerable effort was expended to make the entire series of regulators easy to use and minimize the number of external components. It is not necessary to bypass the output, although this does improve transient response. Input bypassing is needed only if the regulator is located far from the filter capacitor of the power supply Specification RoHS Compliant - Category : Linear Regulatr Package Type: TO-220

7812 Voltage Regulator IC The 7812 IC is a commonly used linear regulator.  Input voltage can range from 12 – 35VDC and it outputs a fixed 12V at over 1A of current and up to 2.2A of surge current. For basic operation, no external components are required. Just hook up the input voltage and ground of the 7812 voltage regulator and you have 5V available on the output. If you are using it at a fair distance from the supply that is providing the input voltage, then a .33uF or larger input filter capacitor is recommended. The part ideally should be a low ESR part such as a Tantalum or Mylar capacitor, but small electrolytic caps generally work fine. Pinout: Pinout of 7812 Voltage Regulator IC Applications: Electronic Communications. LEDs and Flashlights. Load Switches. Electrical Power Supplies. Also check the LM317 Adjustable Voltage Regulator IC available on Iotcart. The LM317 provides a stable, regulated output voltage in the range of 1.2V to 37V and can be adjusted using external resistors. It has a maximum continuous output current of 1.5A, a typical dropout voltage of 1.5V, and operates over a wide range of input voltages (3V to 40V) and temperatures (-40°C to 125°C). The IC features built-in current limiting, thermal shutdown protection, and short-circuit protection. Also check the 7806 Voltage Regulator IC available on the Iotcart website. It operates at an input voltage of 5V, with a maximum input voltage of 35V and a maximum output current of 1.5A. The standby current is 5mA.

8 Ohm 0.5W Speaker An 8 ohm 0.5 watt speaker is an electronic component that converts electrical signals into sound waves. It is typically used in small electronic devices, such as cell phones, portable speakers, and handheld radios, where space is limited and low power consumption is important. The resistance of a speaker, measured in ohms, determines its electrical characteristics and how it interacts with the amplifier or other electronic devices it is connected to. An 8 ohm speaker has a resistance of 8 ohms, which is a moderate impedance level that is suitable for use with a wide range of amplifiers. The power rating of a speaker, measured in watts, determines the maximum amount of power that the speaker can handle without being damaged. A 0.5 watt speaker has a relatively low power rating, which means that it is suitable for use with low-power amplifiers or in applications where high volume is not required. Speakers are used in a wide variety of electronic devices, including cell phones, portable speakers, handheld radios, home theater systems, and computer speakers. They are essential components of these devices, as they allow the user to hear the audio output of the device.

8 Pin IC Base An 8-pin IC base refers to a type of integrated circuit (IC) package that has 8 pins or leads for connecting the IC to a circuit board. These pins are typically arranged in a dual in-line package (DIP) configuration, with two rows of four pins each. 8-pin ICs are often small and simple ICs that are widely used in many electronic devices and appliances, such as timers, oscillators, and digital logic circuits, for example, 555 timer IC , LM358 IC, etc. The 8-pin DIP package is one of the most common IC package formats, and it is often used for ICs that have a small number of input and output pins. This package is relatively easy to work with, as the pins are widely spaced and can be easily inserted into a breadboard or soldered onto a circuit board. This is 8 Pin IC Base with a pin-to-pin spacing of 2.54mm and a width of 7.62mm (300 mil). Features: 8 Pin DIP IC Socket Base Adaptor Molded notch for proper orientation Easy to insert and remove ICs Compatible with 8-pin ICs in dual in-line package (DIP) configuration Reliable and durable design Applications: Circuit prototyping: Facilitates easy testing and swapping of 8-pin ICs during circuit development. Electronic projects: Useful for hobbyists and DIY enthusiasts working on projects involving timers, oscillators, and digital logic circuits. Breadboarding: Compatible with breadboards, making it convenient for temporary circuit setups and experimentation. Embedded systems development: Useful in the prototyping phase of embedded systems where different ICs may need testing. Robotics projects: Can be incorporated into robotics projects that involve 8-pin ICs for control and processing. Automation projects: Suitable for applications requiring small-scale automation using 8-pin ICs.
