To view specs, inventory availability, pricing and delivery, please click on desired part number. LDI1117 series
The LDI1117 series by Diotec are positive linear voltage regulators with low dropout and output currents of up to 1.35 A. They offer a typical voltage drop of 1.15 V at 1 A and can be operated at up to 20 V of input voltage (maximum rating).
Parts are available with adjustable output voltage, ranging from 1.25 V to 13.65 V and set-up by just two additional resistors. Further available are versions offering a fixed output voltage of 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V or 5.0 V.
All versions feature integrated current limiting and thermal shut-down circuits, which prevent damage in case of overload conditions. Furthermore, its internal circuitry comprises of trimmed bandgap reference, ensuring the tight output voltage accuracy of 1% tolerance. Adding of 22 pF at the output is recommended to attenuate transient response and ensure stability.
They are offered in low profile and space saving packages like SOT-223, SO-8 and SOT-89. All these packages are totally lead-free and in full compliance to ROHS and REACH without any exemptions.
