Product Summary

The RC4194N is a dual polarity tracking regulator designed to provide balanced or unbalanced positive and negative output voltages at currents to 200 mA. A single external resistor adjustment can be used to change both outputs between the limits of ±50 mV and ±42V. The RC4194N is designed for local “on-card” regulation, eliminating distribution problems associated with singlepoint regulation. To simplify application the regulator RC4194N requires a minimum number of external parts. The RC4194N is available in three package types to accommodate various power requirements. The K (TO-66) power package can dissipate up to 3W at TA = +25℃. The D 14-pin dual in-line will dissipate up to 1W and the N 14-pin dual in-line will dissipate up to 625 mW.
