Fairchild RC4194 manual

• Simultaneously adjustable outputs with one resistor

to ±42V

• Load current – ±200 mA with 0.04% load regulation

The RC/RM4194 are dual polarity tracking regulators

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.

These devices are designed for local “on-card” regulation,

eliminating distribution problems associated with single-

point regulation. To simplify application the regulators

require a minimum number of external parts.

The device is available in three package types to accommo-

date various power requirements. The K (TO-66) power

package can dissipate up to 3W at TA = +25°C. 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.

• Internal thermal shutdown at TJ = +175°C

• External balance for ±VOUT unbalancing

• 3W power dissipations
