Linear Technology Corp. introduces the LTM8001, a step-down µModule® (micromodule) regulator consisting of an array of five low noise 1A linear regulators. The linear regulators are also configurable to deliver 2A, 3A, 4A or 5A, depending on the number and combination of current shared outputs.

Housed in a 15mm x 15mm x 3.42mm ball grid array (BGA) package, the LTM8001 provides high efficiency conversion from an input source, ranging from 6V to 36V, by powering the five low noise linear regulators from an onboard synchronous step-down converter. Each output voltage is adjustable from 0V to 24V. The LTM8001 is designed to supply multirail systems based on FPGAs, DSPs, ASICs and microprocessors.

Each of the LTM8001's five linear regulars has an adjustable output voltage ranging from 0V to 24V with ±2% accuracy over temperature. Output noise is just 90µVRMS over the 10Hz to 1MHz frequency range. The step-down regulator features a user-adjustable current limit accurate within ±10%.

The LTM8001 is available with guaranteed operation over the -40°C to +125°C and -55°C to +125°C internal temperature range. Pricing starts at $17.40 each for 1,000 piece quantities. The LTM8001 is available for immediate delivery from stock. For more information, visit www.linear.com/product/LTM8001.
