LM337 Typical application
17
* The 10 µF capacitors are optimal to improve ripple rejection.
* When CL is larger than 20 µF, D1 protects the LM337 in case the input supply is shorted.
** When C2 is larger than 10 µF and V
O
is larger than - 25 V, D2 protects the LM337 in case the output is
shorted.
