L78S 2A Linear Voltage Regulator, STMicroelectronics


STMicroelectronics L78S series positive voltage regulators are for use in fixed voltage regulation. There are no external parts required unless you want to adjust the outputs. The linear voltage regulators feature safe area protection, internal current limiting and thermal shut-down making them a robust device. STMicroelectronics regulators can offer local on-card regulation which can eliminate any distribution problems associated with single point regulation.

Three-terminal positive regulators in TO220 package

Output current up to 2 A/ Range of fixed output voltages

Thermal protection, short circuit protection, output transition SOA protection
