Positive Linear Voltage Regulators with Low Dropout and Output Currents of up to 1.35 A
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 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 with ROHS and REACH without any exemptions.
