Linear Current Regulators

Linear current regulators provide a precise constant current starting from a varying input voltage source. They are ideal for replacing discrete-component LED driving solutions in low-voltage applications including 5 V, 12 V or 24 V supplies, providing benefits in terms of precision, integration and reliability.
An external resistor is used to set the output current up to 2 A with ± 10 % precision; a dedicated pin can be used for PWM dimming. An open-drain pin output provides information on load disconnection conditions.
