Overview
The L7905CV is a fixed negative linear voltage regulator from the L79 series, manufactured by EVVO. It provides a stable -5 V output with a maximum current capacity of 1.5 A. The device operates within an input voltage range of -7 V to -35 V and features a dropout voltage of 1.4 V at 1 A load. Key electrical specifications include a static current of 3 mA, line regulation of 100 mV, load regulation of 100 mV, and typical power supply rejection ratio (PSRR) of 60 dB. It is housed in a TO-220-3 through-hole package and supports an operating temperature range from 0°C to +150°C.
Feature Summary
- Provides fixed negative voltage regulation for single-output applications
- Includes internal thermal overload protection and safe area compensation
- Utilizes TO-220-3 through-hole packaging for robust mounting
Applications
- Negative power supply rails in dual-supply electronic systems
- General-purpose voltage regulation in industrial equipment
- Power management circuits requiring stable negative bias
Procurement Notes
Verify manufacturer authenticity as multiple vendors list this part number. Confirm RoHS compliance status and specific datasheet version before ordering. Ensure the supplier source matches the required quality standards for your application. Cross-reference the component marking with official documentation to avoid counterfeit risks during procurement.
Selection Notes
Select this component when a fixed negative voltage is required in designs utilizing positive regulators for complementary rails. The TO-220-3 package suits applications needing moderate heat dissipation without active cooling. Verify that the input voltage remains within the specified limits to ensure proper regulation and prevent damage to the device under varying load conditions.
Part Context
This component belongs to the L79 series of three-terminal negative linear regulators. It serves as a complement to the L78 series positive regulators, enabling symmetric power supply designs. The L7905 variant specifically targets -5 V generation, widely used in analog circuits and operational amplifier biasing where dual polarity supplies are standard.
Replacement Considerations
Compatible substitutes include LM7905, MC7905, and L7905CV-DG. These parts share identical pinouts and electrical characteristics, allowing direct replacement in existing PCB layouts without circuit modification.
