1 A Low Dropout Positive
Voltage Regulator
LD1117A12/ADJ-LD1117A50/ADJ
1A Low Dropout Positive
Voltage Regulator
General Description
LD1117A is a three terminal low dropout positive
voltage regulator. It provides current limiting and thermal shut down and its circuit includes a trimmed Bandgap reference to assure output
voltage accuracy for both fixed output
voltage version and adjustable output
voltage version. Current limit is trimmed to ensure specified output current and controlled short-circuit current.On-chip thermal shutdown provides protection against any combination of overload and ambient temperature that would create excessive junction temperature
There are 7 Fixed output
voltages :1.2V, 1.5V,1.8V, 2.5V ,2.85V,3.3V an 5.0V. There are also an adjustble version provide output
voltage from 1.25V to 12V with 2 external resisitors. They are suitable for applications that required supply current up to 1 A.
LD1117A series are available in SOT-223 ,SOT-89 ,TO-220,DPAK (TO-252) and D2PAK (TO-263) Packages
