79M05 TO-220-3 Linear Voltage Regulator

Description

• Voltage Regulation: The 79M05 is known for its ability to regulate the output voltage to a fixed -5 volts. It provides a steady and reliable negative voltage source for powering other components in an electronic circuit.
• Voltage Input Range: The 79M05 requires an input voltage slightly higher (less negative) than the desired -5V output voltage. Typically, it can handle input voltages ranging from around -7V to -25V, depending on the specific manufacturer and model.
• Output Current: The maximum output current the 79M05 can supply depends on factors such as input voltage, thermal management, and the specific model, but it can often provide currents in the range of 0.5A to 1A. It can maintain a stable -5V output within its specified current range.
• Regulation: The 79M05 offers fixed voltage regulation, ensuring that the output voltage remains close to -5V, even when there are variations in the input voltage or load conditions.
• Package Type: These regulators typically come in a TO-220-3 package, which is a standard through-hole package with three pins: input (Vin), ground (GND), and output (Vout).
• Applications: Negative voltage regulators like the 79M05 are commonly used in various electronic applications where a stable and precise negative voltage source is required.
• Heat Dissipation: For high-current applications or when the input voltage is significantly less negative than the output voltage, a heat sink may be required to dissipate heat and prevent the regulator from overheating.
• Output Protection: Some models may include protection features such as over-temperature shutdown and over-current protection.
• Use of Decoupling Capacitors: It is common practice to include decoupling capacitors (typically in the range of 100nF to 10µF) at the input and output to stabilize the regulator and reduce noise.
