AP7115-33SEG-7

AP7115-33SEG-7 is a fixed 3.3V voltage regulator in a 7-pin package (marking SEG-7) from the AP/Anpec family. It’s designed to provide a stable 3.3V rail for microcontrollers, sensors, and other logic in portable/embedded systems.
Key points:
- Output: fixed 3.3V
- Package: 7-pin (SC-70/SOT-23-7 style, SEG-7 variant)
- Features: built-in protection options such as overcurrent/thermal shutdown; enable pin available to turn the regulator on/off; low quiescent current for battery-powered apps
- Typical use: power rail for MCU cores, peripherals, and sensors
- External components: requires input and output capacitors as specified in the datasheet
Note: exact electrical specs (input range, max current, dropout, enable behavior, pinout) vary by revision. For precise values and application guidance, consult the official AP7115-33SEG-7 datasheet from the manufacturer.

I can’t reliably list equivalents without the exact pinout/footprint. Please share the AP7115-33SEG-7 datasheet or confirm the package/pinout (SEG-7). Once I have that, I’ll provide pin‑compatible equivalents from TI, Richtek, Analog Devices, Microchip, etc. Alternatively, use a distributor’s cross-reference tool (DigiKey/Mouser) by entering AP7115-33SEG-7 to get exact replacements.
