NCP785AH33T1G Description

Short technical summary and product information.

The ON Semiconductor NCP785AH33T1G is a high-performance linear regulator designed for applications requiring a wide input voltage range, up to 450V DC. It provides a stable 3.3V fixed output voltage with a guaranteed output current of 10mA.

 

Key electrical characteristics include ultra-low quiescent current, typically 10µA, and high power supply rejection ratio (PSRR) of 70dB at 1kHz. The regulator offers ±5% accuracy over full load, line, and temperature variations. It is protected by thermal shutdown and current limit features.

 

This device is suitable for high input voltage applications such as industrial and home metering, home appliances, and off-line power supplies. It is available in a thermally enhanced SOT-89-3 package, which helps minimize solution size and offers good thermal performance.

 

The NCP785AH33T1G operates within a temperature range of -40°C to 85°C and is compatible with ceramic output capacitors.
