RH3080MK DICE/DWF Adjustable 0.9A Single Resistor Low Dropout Regulator
FEATURES DESCRIPTION
n
Outputs May Be Paralleled for Higher Current and
The RH3080 is a 0.9A 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 36V. Multiple n
10µA 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 pass ELDRS Pass 100kRad(Si) transistor. A 2.2µF capacitor on the output with an ESR of n Displacement Damage Defects (DDD) Up to 1E12 less than 0.5Ω is adequate to ensure stability. Applications Neutrons/cm2 with large output load transients require a larger output n Single Event Latchup (SEL) Threshold Linear Energy capacitor value to minimize output voltage change. Input Transfer (LET) ≥110MeV.cm2/mg at TCASE = 100°C circuitry ensures output safe operating area current limit- n MIL-PRF-38535 Class V Compliant 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.
