RH3083MK DICE/DWF Adjustable 2.8A Single Resistor Low Dropout Regulator
Features DescriPtion
n
Outputs May Be Paralleled for Higher Current and
The RH3083 is a 2.8A low dropout linear regulator with a
Heat Spreading
unique architecture featuring a precision current source n
Single Resistor Sets Output Voltage
and voltage follower which allows the output to be pro- n
Output Adjustable to 0V
grammed to any voltage between zero and 18V. Multiple n
50µA SET Pin Current: 1% Initial Accuracy
regulators can be paralleled to increase total output current n Total Ionizing Dose (TID) Tolerance, per TM1019.8, and spread heat over a system PC board with no need for MIL-STD-883 up to: heat sinking. The pass transistor collector can be brought • 200kRad (Si), per Condition A, at 50Rads(Si)/sec out independently of the circuit supply voltage to allow • 100kRad (Si), per Condition D, at 10mRads(Si)/sec dropout voltage to approach the saturation limit of the • ELDRS Pass 100kRad(Si) pass transistor. A small 10µF capacitor on the output with n Single Event Latchup (SEL) Threshold Linear Energy an ESR of less than 0.5Ω is adequate to ensure stability. Transfer (LET) ≥ 110MeV • cm2/mg at TCASE = 100°C Applications with large output load transients require a n MIL-PRF-38535 Class V Compliant larger output capacitor value to minimize output voltage change. Input circuitry ensures output safe operating area current limiting and thermal shutdown protection. The rated output current of an RH3083-based part is fixed by internal wire length/resistance. Linear Technology dice element evaluations are based on parts rated for 2.8A output current.
