RC4194 Datasheet | Fairchild Semiconductor

.fairchildsemi. Dual Tracking Voltage Regulators Features - Simultaneously adjustable outputs with one resistor to ±42V - Load current - ±200 m A with 0.04% load regulation - Internal thermal shutdown at TJ = +175°C - External balance for ±VOUT unbalancing - 3W power dissipations Description The RC/RM4194 are dual polarity tracking regulators designed to provide balanced or unbalanced positive and negative output voltages at currents to 200 m A. A single external resistor adjustment can be used to change both outputs between the limits of ±50 m V and ±42V. These devices are designed for local “on-card” regulation, eliminating distribution problems associated with singlepoint regulation. To simplify application the regulators require a minimum number of external parts. The device is available in three package types to acmodate 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 m W.
