NCP703SN33T1G Description

Short technical summary and product information.

The ON Semiconductor NCP703SN33T1G is a 300 mA, ultra-low quiescent current, ultra-low noise LDO voltage regulator. It provides a stable and accurate 3.3V output voltage, suitable for noise-sensitive RF applications such as power amplifiers in satellite radios, infotainment equipment, and precision instrumentation. The device operates with an input voltage range of 2.0 V to 5.5 V and features very low dropout voltage (180 mV typical at 300 mA).

 

Key electrical characteristics include ultra-low noise performance of 13 µVRMS from 100 Hz to 100 kHz, high Power Supply Rejection Ratio (PSRR) of 68 dB at 1 kHz, and ±2% accuracy over load, line, and temperature variations. It incorporates internal soft-start to limit inrush current and active output discharge for fast turn-off. Protection features include over current and over temperature shutdown.

 

The NCP703SN33T1G is available in a compact 5-TSOP package, designed for surface mount applications. Its ultra-low quiescent current and dynamic IQ management optimize performance for battery-operated portable devices, offering low quiescent current consumption at light-load conditions and good dynamic performance.
