The RT9041A/B are low voltage, low dropout linear regulators with an external bias supply input. The bias supply drives the gate of the internal N-Channel pass transistor, making these devices ideal for applications that require low voltage outputs from low voltage inputs. RT9041A and RT9041B provide the fixed version from 1V to 2V with 0.1V increment. Besides, RT9041B provides more feature by using external resistors as adjustable output voltage. The RT9041A/B include a current limit and thermal shutdown that protects the regulator in the event of a fault condition.
The RT9041A/B is available in a SOT-23-6 package.
