产品概览
The onsemi NCP1117DT33RKG is a 1A low-dropout (LDO) linear voltage regulator providing a fixed 3.3V output. With a maximum dropout voltage of 1.2V at 800mA, it can operate from input voltages up to 20V. The DPAK package provides excellent thermal performance for applications requiring moderate output current.
