BA4302 is a voltage regulator IC manufactured by ROHM Semiconductor.

The BA4302 is a voltage regulator IC manufactured by ROHM Semiconductor. Below are its key specifications, descriptions, and features:

Specifications:

  • Input Voltage Range: 4.5V to 18V
  • Output Voltage: Fixed (3.3V, 5V, or adjustable)
  • Output Current: 500mA (max)
  • Dropout Voltage: 0.5V (typical at 500mA)
  • Line Regulation: ±0.2% (typical)
  • Load Regulation: ±0.5% (typical)
  • Quiescent Current: 1mA (typical)
  • Operating Temperature Range: -40°C to +85°C
  • Package: TO-252-5 (HSOP5)

Descriptions:

  • The BA4302 is a low-dropout (LDO) linear voltage regulator designed for stable power supply applications.
  • It features built-in overcurrent protection, thermal shutdown, and short-circuit protection.
  • Suitable for automotive, industrial, and consumer electronics due to its wide input voltage range and reliability.

Features:

  • Low Dropout Voltage: Ensures efficient regulation even with small input-output differentials.
  • High Ripple Rejection: Reduces noise in the output voltage.
  • Built-in Protection Circuits: Includes overcurrent, thermal shutdown, and short-circuit protection.
  • Adjustable Output (for some variants): Allows flexibility in setting the desired output voltage.
  • Compact Package: HSOP5 (TO-252-5) package for space-saving PCB designs.

For exact part number variants (fixed/adjustable), refer to ROHM's official datasheet.
