... A Low-Dropout Positive Fixed and Adjustable Voltage Regulators The NCP1117LP is the low power version of the popular NCP1117 family of low dropout voltage regulators, with reduced quiescent current intended primarily for high volume consumer applications over the 0 to 125 degree temperature range. Capable of providing an output current in excess with a dropout voltage of 1 ...

... Introduction The NCP1117LP is a low dropout positive fixed or adjustable mode regulator with 1 A output capability. This LDO is guaranteed to have a significant reduction in dropout voltage along with enhanced output voltage accuracy and temperature stability when compared to older industry standard three−terminal adjustable regulators. ...

... Protection Diodes The NCP1117LP family has two internal low impedance diode paths that normally do not require protection when used in the typical regulator applications. The first path connects between V and V , and it can withstand a peak out in surge current of about 15 A. Normal cycling of V generate a current surge of this magnitude. Only when V is shorted or crowbarred to ground and C 50 mF, it becomes possible for device damage to occur ...
