n MIL-PRF-38535 Class V Compliant The RH3083 is a 2.8A low dropout linear regulator with a
unique architecture featuring a precision current source
and voltage follower which allows the output to be programmed to any voltage between zero and 18V. Multiple
regulators can be paralleled to increase total output current
and spread heat over a system PC board with no need for
heat sinking. The pass transistor collector can be brought
out independently of the circuit supply voltage to allow
dropout voltage to approach the saturation limit of the
pass transistor. A small 10µF capacitor on the output with
an ESR of less than 0.5Ω is adequate to ensure stability. …
