This assumes a zener has 20PPM/°C maximum drift and about 10 times lower noise than the regulator. LM137A SERIES LM137A SERIES Multiple Tracking Regulators In the application shown below, regulator #2 to “N” will track regulator #1 to within ±24mV initially, and to ±60mV over all load, line, and temperature conditions. If any regulator output is shorted to ground, all other outputs will drop to -2V. Load regulation of regulators 2 to “N” will be improved by VOUT / 1.25V compared to a standard regulator, so regulator #1 should be the one which has the lowest load current. 2 µF C3 1 0µF R2 C1 1 µF SO LID TAN TALU M R 2* 7V R3 1 .5 k 1% R1 1k 1% 1 µF SO LID TANT ALUM AD J VIN – VIN VOU T R EG #1 1 N4 0 0 2 AD J VIN – VIN VOU T R1 1 20 Ω – VO U T1 * R2 = IP337A IP3 17A VIN +VIN ADJ VOU T ( VO U T ) – 9 08 Ω 9.08 x 10 -3 – VO U T IP137A 2 µF AD J VIN VOU T R EG #2 1 N4 0 0 2 1 µF SO LID TANTA LU M +VO U T – VO U T2 IP137A R1* * 1 00 Ω 1% 2. 2 µF D1 1N40 02 1 µF SO LID TANTA LU M 1 0µ F R2 5k 1% 2 µF AD J 1 N4 0 0 2 R3 5k VIN VOU T R EG #N – VO UT N 1 0µ F R4 5k 1% 2. 2 µF D2 1N40 02 I P 13 7 A R5* * 1 00 Ω 1% ADJ VIN – VIN VOU T – VO U T C1 1 µF AD J (– ) VIN VOU T SO LID TANA TALU M IP3 37A IP337A * Solid Tantalum ** R1 or R5 may be trimmed slightly to improve tracking.
