L7905CV Overview
The L7905CV is a –5 V fixed negative linear regulator from the ST L79 series in a TO-220 package. It provides local on-card regulation, and since it offers the same voltage options as the L78 positive series it suits split power supplies.
Key Features
- Output current up to 1.5 A
- –5 V fixed output
- Thermal overload protection
- Short-circuit protection
- Output SOA protection
- Output tolerance 4 % at 25 °C (C version)
Applications
- Local on-card negative-rail regulation
- Split (±) power supplies with an L78 positive regulator
- Industrial control power supplies
