LM7905 5V TO-220 Negative Voltage Regulator IC

LM7905 5V TO-220 Negative Voltage Regulator IC

The LM7905 is a commonly used negative voltage regulator IC that provides a regulated -5V output with up to 1.5A of current handling. Like its positive-regulator counterparts, it’s housed in a TO-220 package and dissipates excess voltage as heat, so a heatsink is recommended for sustained higher-current use. It’s the go-to choice whenever a circuit — such as an op-amp supply — needs a negative rail alongside a positive one.

Features

• Fixed -5V regulated output
• Up to 1.5A output current
• Internal thermal overload and short-circuit protection
• Low ground-pin current allows output to be boosted with a resistor divider
• Standard 3-pin TO-220 package

Applications

• Dual-rail power supplies (with a positive regulator)
• Op-amp negative supply rail
• Regulated power supply designs
• Current-limiting applications

Package Includes

• 1 x LM7905 -5V Voltage Regulator IC
