Product Description

The L7912ACV is a Single Gauge 3-terminal Negative Voltage Regulator with -12V output voltage. It is available in several fixed output voltages, making it useful in a wide range of applications. This regulator can provide local on-card regulation, eliminating the distribution problems associated with single point regulation, furthermore, having the same voltage option as the L78 positive standard series, this is particularly suited for split power supplies. If adequate heat sinking is provided, it can deliver over 1.5A output current. Although designed primarily as fixed voltage regulators, this device can be used with external components to obtain adjustable voltages and currents.
Thermal overload protection
Short-circuit protection
Output transition SOA protection
Output tolerance 2% (AC version) or 4% (C version) at 25°C
