Rethinking Radiation Hardened Low Dropout Regulators IN LRH3083 VCONTROL 50µA + VIN + + – VCONTROL OUT VOUT SET RSET COUT CSET VOUT = 50µA • RSET 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 0V and 18V. Multiple regulators can be easily paralleled to increase total output current and spread heat over a system PC board with no need for heat sinking.
