Full output current not available
at high input-output voltages
*The 10 μF capacitors are optional to improve ripple rejection

*When CL is larger than 20 μF, D1 protects the LM137 in case the input supply is shorted
**When C2 is larger than 10 μF and −VOUT is larger than −25V, D2 protects the LM137 in case the output is shorted
