Descripción general

Description

The L4931CZ33-AP is a fixed 3.3 V buck (step-down) regulator from STMicroelectronics, part of the L4931 family. The -AP suffix indicates a specific package/qualification variant (e.g., automotive-grade option) and an 8-pin package.
Key points:
- Type: fixed-output switch-mode regulator that down-converts a higher input voltage to 3.3 V.
- Control: uses current-mode PWM with soft-start and built-in protections (overcurrent, thermal shutdown).
- External components: requires external energy-storage parts per datasheet (e.g., inductor, diode or synchronous rectifier, input/output capacitors).
- Applications: powering microcontrollers, sensors, and other low-voltage circuits, including automotive systems where efficiency and protection matter.
Usage notes:
- Check the datasheet for exact pinout, recommended external components, input range, efficiency, and layout guidelines.

Package

SOT-23-5 (SC-74A) surface-mount package.

Pinout

- Pin count: 8 pins (SO-8 package)
- Function: Fixed-output 3.3 V buck (step-down) switching regulator with an integrated high-side switch. Converts a higher input voltage to 3.3 V; requires external inductor and capacitors. Typical pins include VIN, GND, SW, FB, EN, BOOT, and NC/EP per the datasheet.

Manufacturer

- Manufacturer: STMicroelectronics (ST)
- What kind of company: A global multinational semiconductor company that designs, manufactures, and markets a wide range of integrated circuits and discrete semiconductors (including power management, microcontrollers, sensors, and automotive ICs).

Application

Fixed 3.3 V low-dropout regulator. Used to supply a stable 3.3 V rail in automotive, industrial, and consumer electronics, including microcontroller and sensor front-ends, analog/digital circuits, and compact portable devices.
