SNVS778D – MAY 1999 – REVISED APRIL 2013

Typical Applications

Figure 11. Adjustable Lab Voltage Regulator

Full output current not available

at high input-output voltages

*The 10

μF capacitors are optional to improve ripple rejection

Figure 12. Current Regulator

Figure 13. Negative Regulator with Protection Diodes

*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
