Applications Information General Description The SC560 is a family of dual output linear regulator devices intended for applications where low dropout voltage, low supply current, and low output noise are critical. Each device provides a very simple, low cost solution ...
Page 11
Applications Information (continued) The values of the resistors in the voltage divider network can be calculated using the equation OUT REF R 2 where V = 1V. The value of R2 should be 100kΩ ...
