Description
The RH3080 is a 0.9A low dropout linear regulator with a
unique architecture featuring a precision current source
and voltage follower which allows the output to be pro-
grammed to any voltage between zero and 36V. 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 2.2µF capacitor on the output with an ESR of
less than 0.5Ω is adequate to ensure stability. Applications
with large output load transients require a larger output
capacitor value to minimize output voltage change. Input
circuitry ensures output safe operating area current limit-
ing and thermal shutdown protection. The rated output
current of an RH3080-based part is fixed by internal wire
length/resistance. Linear Technology dice element evalu-
ations are based on parts rated for 0.9A output current.
