The LT3507 is a monolithic switching regulator that combines three independent switching regulators with a low dropout linear regulator in a compact 5mm × 7mm QFN package.
The document describes the LT3507, a compact power supply solution combining three independent monolithic switching regulators and a low dropout linear regulator. It is designed to meet varied demands of multiple power supplies by providing sequenced voltages, shutdown options, and clean low-noise outputs.
Key features include internal power switches for each channel, independent input supplies, run/track/soft-start controls, and power good indicators. The device operates from a maximum input voltage of 36V and includes undervoltage and overvoltage protection.
| Package Type | 5mm x 7mm QFN |
|---|---|
