General Description
The APL5930 is a 3A ultra low dropout linear regulator. The IC needs two supply voltages, one is a control voltage (V
) for the control circuitry, the other is a main supply
CNTL
voltage (VIN) for power conversion, to reduce power dissi­pation and provide extremely low dropout voltage. The APL5930 integrates many functions. A Power-On­Reset (POR) circuit monitors both supply voltages on VCNTL and VIN pins to prevent erroneous operations. The functions of thermal shutdown and current-limit pro­tect the device against thermal and current over-loads. A POK indicates the output voltage status with a delay time set internally. It can control other converter for power sequence. The APL5930 can be enabled by other power systems. Pulling and holding the EN voltage below 0.4V shuts off the output. The APL5930 is available in a SOP-8P package which features small size as SOP-8 and an Exposed Pad to reduce the junction-to-case resistance to extend power range of applications.

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020D for MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by weight).
