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
L78M Series Linear Voltage Regulator, STMicroelectronics
The L78M series positive linear voltage regulators by STMicroelectronics all have fixed voltage outputs from 5V up to 24 V with a 500mA current output. They are three terminal regulator ICs that are available in a range of packages from TO220, DPAK and IPAK. These devices are suitable for use in many applications including local on-card regulation and power distribution systems. The internal current limiting, thermal shutdown and safe operating area protection make them durable. There are no external components required unless you want to adjust the voltage and current outputs.
