Legislation and Compliance
RoHS Certificate of Compliance
EU Directives 2011/65/EU and 2015/863 restrict the use of the 10 substances below in the manufacture of specified types of electrical equipment.
Whilst this restriction does not legally apply to components, it is recognised that component “compliance” is relevant to many customers.
RS definition of RoHS Compliance:
- The product does not contain any of the restricted substances in concentrations and applications banned by the Directive,
- and for components, the product is capable of being worked on at the higher temperatures required by lead–free soldering
The restricted substances and maximum allowed concentrations in the homogenous material are, by weight:
| Substance | Concentration |
| Lead | 0.1% |
| Mercury | 0.1% |
| PBB (Polybrominated Biphenyls) | 0.1% |
| PBDE ( Polybrominated Diphenyl Ethers) | 0.1% |
| Hexavalent Chromium | 0.1% |
| Cadmium | 0.01% |
| DEHP (Bis (2-Ethylhexl) phthalate) | 0.1% |
| BBP (Benzyl butyl phthalate) | 0.1% |
| DBP (Dibutyl phthalate) | 0.1% |
| DIBP (Diisobutyl phthalate) | 0.1% |
The supplier of the item listed below has informed RS Components that the product is "RoHS Compliant".
RS Components has taken all reasonable steps to confirm this statement. Information relates only to products sold on or after the date of this certificate.

Product Details
Linear Voltage Regulators, STMicroelectronics
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
