NOTES: (1) For ambient temperature above +70
°
C, the input voltage is 12.5V (max). The input voltage remains 16V (max) if case temperature is kept below +85
°
C.
(2) External capacitor across P+ to V
–
pins and 12" of #24 wire to V
. (3) Reference UL544, paragraph 27.5, Leakage Current. (4) See Typical Characteristics.
(5) A minimum output current of 3mA at each output is recommended to maintain output voltage accuracy.
