|---|---|---|---|
| FFF Compatibility | Pin 4 is an EN (Enable) pin instead of NC (Not Connected); it must be tied high to enable the regulator and cannot be left floating, which may require a PCB layout check or modification.Matches the physical U-DFN2020-6 package size and mounting style.Meets the 3.3V fixed output and 300mA current requirements while exceeding the input voltage rating. | Features the exact same pin assignments (Pin 1: VOUT, Pin 3: GND, Pin 6: VIN, with Pins 2, 4, 5 as NC) and footprint as the target part.Same U-DFN2020-6 (Type C) physical dimensions and land pattern.Provides only 150mA maximum output current compared to the original part's 300mA. | |
 AI Summary | AP7370-33FDC-7 by Diodes Incorporated: Linear Voltage Regulator IC Positive Fixed 1 Output 300mA U-DFN2020-6 (Type C). | This is the official manufacturer-recommended replacement for the obsolete AP7370-33FDC-7. It matches the 300mA output capability and 3.3V fixed voltage, but introduces an EN pin on Pin 4 which was previously NC, requiring verification of the board layout.
| This alternative is a true pin-to-pin drop-in replacement that requires zero PCB modification because it omits the Enable pin (leaving Pins 2, 4, and 5 as NC). However, it is limited to a 150mA maximum load, making it suitable only if the system's actual current draw does not exceed this threshold.
