The LTM8001 is a 36VIN, 5A step-down μModule® (power module) regulator with a 5-output configurable LDO array. Operating over an input voltage range of 6V to 36V, the LTM8001 buck regulator supports an output voltage range of 1.2V to 24V. Following the buck regulator is an array of five 1.1A linear regulators whose outputs may be connected in parallel to accommodate a wide variety of load combinations. Three of these LDOs are tied to the output of the buck regulator, while the other two are tied together to an undedicated input.
The low profile package (3.42mm) enables utilization of unused space on the bottom of PC boards for high density point of load regulation. The LTM8001 is packaged in a thermally enhanced, compact (15mm × 15mm) and low profile (3.42mm) overmolded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8001 is available with SnPb (BGA) or RoHS compliant terminal finish.

Product Lifecycle Production
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
Evaluation Kits (1)
Demo circuit 1818A features the LTM8001 μModule regulator that includes a 5A switching regulator and an array of five 1.1A low noise LDOs. The demo board operates from a 6V to 36V input and is configured so the switching regulator provides an output that also powers the LDOs. The LDOs in turn provide three outputs – one from a single LDO and two outputs each formed by paralleling two LDOs together.
