... CMOS construction, the TC962 can source as much as 8mA versus the 7662’s 20mA capability inverter, the TC962 can put out voltages as high as 18V and as low as 3V without the need for external diodes. The output impedance of the device is a low 28 (with the proper capacitors), voltage conversion efficiency is 99 ...

... TC962 Pin 1, which is used as a test pin on the 7662 voltage reference zener on the TC962. This zener (6. mA) has a dynamic impedance of 12 and is intended for use where the TC962 is supplying current to external regulator circuitry and a reference is needed for the regulator circuit. (See applications section ...
