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
鹵50
mV and
鹵42V.
These devices are designed for local 鈥渙n-card鈥?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 T
A
= +25擄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.
