Specification

Description

The LM7805 is a voltage regulator integrated circuit (IC) designed to provide a stable +5V output voltage from a higher unregulated input voltage source.

Here's a Detailed Description of its main Features and Specifications:

Voltage Regulation: The LM7805 regulates the output voltage to +5V, ensuring a constant voltage despite changes in the input voltage or load conditions.

Output Current: It is capable of supplying a continuous output current of up to 1A (ampere), making it suitable for powering a wide range of low to medium-power electronic circuits.

Input Voltage Range: The LM7805 typically operates with an input voltage range of 7V to 25V. However, it can handle higher input voltages up to 35V in certain applications, although the excess voltage will be dissipated as heat.

Three-Terminal Device: The LM7805 has three terminals: Vin (input), Vout (output), and GND (ground). The input voltage is applied to the Vin terminal, the regulated +5V output is obtained from the Vout terminal, and the GND terminal is connected to the circuit's ground reference.

Thermal Overload Protection: The IC includes built-in thermal overload protection, which safeguards the device by shutting it down in case of excessive temperature rise due to high ambient temperature or prolonged overcurrent conditions.

Output Capacitor: It is recommended to use an output capacitor (typically in the range of 0.1?F to 1?F) to improve the transient response and stability of the regulator.

Applications:

The LM7805 is widely used in various electronic devices and circuits where a stable +5V power supply is required, such as microcontrollers, logic circuits, sensors, and many other digital and analog components.

The LM78CV Series voltage regulator is a fixed output, three-terminal precision positive voltage regulator in a 3 3-pin TO-220 package. This regulator can provide local on-card regulation by eliminating distribution problems associated with single-point regulation.

The LM78CV series fixed voltage regulator is designed with thermal overload protection that shuts down the circuit when subjected to excessive power. These regulators can provide local regulation on the card, eliminating distribution problems associated with a single point of regulation. The LM7805, like most other regulators, is a three-pin IC.
  • Pin 1 (Input Pin): The Input pin is the pin that accepts the incoming DC voltage, which the voltage regulator will eventually regulate down to 5 volts.
  • Pin 2 (Ground): The ground pin establishes the ground for the regulator.
  • Pin 3 (Output Pin): The Output pin is the regulated 5-volt DC.

Good items, no anti-static bag

Ordered these and I'm happy. They are the L7805CV and output 5v.

My voltage is now regular

I used this to bring a 12V input down to 5V so I could power an ESP8266 dev board. It works! But it gets a bit warm at that load (~40C) so you may want to get a heat sink or something.
