with an effective source impedance of less than 1.0 Ω. This
regulator is convenient for a tracking dc reference for dc
coupling the output to an RF modulator. Typical turn–on drift
for the regulator is approximately –30 mV over 1 to 2 minutes
in otherwise stable ambient conditions.

Power Supplies
The MC1377 is designed to operate from an unregulated
10 V to 14 Vdc power supply. Device current into Pin 14 with
open output is typically 35 mA. To provide a stable reference
for the ramp generator and the video output, a high quality
8.2 V regulator can supply up to 10 mA for external uses,

SUMMARY
The preceding information was intended to detail the
application and basis of circuit choices for the MC1377. A
complete MC1377 application with the MC1374 VHF
modulator is illustrated in Figure 17. The internal schematic
diagram of the MC1377 is provided in Figure 8.
