... BZX97C15 PR SI FUNCTIONAL DESCRIPTION The L4936E is a monolithic integrated dual volt- age regulator, based on the STM modulator volt- age regulator approach. Several outstanding fea- tures and auxiliary functions are implemented to meet the requirements of supplying microproces- sor systems in automotive applications. Neverthe- less suitable also in other applications where two stabilized voltages are required ...

... L4936E The output 2 regulator can be switches OFF via the enable input. Connecting a resistor divider R OUT2 pin the output voltage 2 can be pro- grammed to the value OUT2 OUT1 R with R = 60K to 150K and V ADJ 5.05V. For an exact calculation the temperature coeffi- cient (Tc -2000pprm) of the internal resistor (R ) must be taken into account ...
