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 small 2.2μF capacitor on the output with
an ESR of less than 0.5Ω is adequate to insure stability.
Applications with large output load transients require a
larger output capacitor value to minimize output voltage
change. Input circuitry insures output safe operating area
current limiting and thermal shutdown protection. The
rated output current of an RH3080-based part is fixed by
internal wire length/resistance. Linear Technology dice
element evaluations are based on parts rated for 0.9A
output current.
