Features
• Simultaneously adjustable outputs with one resistor
to ±42V
• Load current – ±200 mA 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 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.
