IR Presents New IRU1011-33 LDO Regulator

January 26, 2003 by Jeff Shepard

International Rectifier Corp. (IR, El Segundo, CA) introduced the IRU1011-33, a fixed-output, linear voltage regulator capable of providing a low dropout (LDO) voltage and a continuous current up to 1.3A with a single 5V input. The device is stable with low-value, low-cost ceramic capacitors, enabling compact designs at lower cost and lower noise compared with circuits using tantalum capacitors, according to the company. Applications for the new LDOs include power management for hard disk drives and ADSL and cable modems.

The IRU1011-33 is designed to meet current transient response up to 1.3A/ms and provides an initial voltage reference with two percent accuracy. The new LDO includes built-in output current limiting and internal thermal shutdown.

Pricing for the new IRU1011-33CH regulator is $0.37 each in 10,000-unit quantities.
