• Output Current: 400mA (max)
• Dropout Voltage: Low (typically around 0.2V at full load)
• Input Voltage Range: Up to 16V (varies by model)
• Line Regulation: ±0.05% (typical)
• Load Regulation: ±0.1% (typical)
• Operating Temperature Range: -40°C to +85°C
• Package Type: SOT-89-5 (miniature surface-mount package)

Descriptions:

The LD-404MG is a low-dropout linear regulator designed for stable voltage supply in compact electronic devices. It features high ripple rejection, low quiescent current, and built-in protection circuits such as overcurrent and thermal shutdown.

Features:

• Low Dropout Voltage: Ensures efficient operation even with small input-output differentials.
• High Ripple Rejection: Reduces noise for cleaner power delivery.
• Low Quiescent Current: Minimizes power consumption in standby mode.
• Built-in Protections: Includes overcurrent and thermal shutdown for reliability.
• Compact Package: SOT-89-5 package saves board space.
