NCP702SN18T1G

The NCP702SN18T1G from ON Semiconductor is a 200 mA linear voltage regulator designed for noise-sensitive applications. It provides a stable and accurate 1.8V output with ultra-low noise and high Power Supply Rejection Ratio (PSRR), making it suitable for RF applications.

Key electrical specifications include an operating input voltage range of 2.0 V to 5.5 V, an ultra-low quiescent current of typically 10 µA, and a very low dropout voltage of 140 mV at 200 mA. The device features ±2% accuracy over the full load, line, and temperature range. It also includes thermal shutdown and current limit protections, as well as internal soft-start to limit turn-on inrush current.

This regulator is stable with a 1 µF ceramic output capacitor and is available in a 5-TSOP package (SOT-23-5 Thin). Its operating temperature range is -40°C to 125°C. Typical applications include PDAs, mobile phones, GPS, smartphones, wireless handsets, and other battery-powered devices requiring clean power supplies.

The device does not require an additional noise bypass capacitor for ultra-low noise performance. It also employs an Adaptive Ground Current feature for low ground current consumption during light-load conditions, optimizing performance for battery-operated portable applications.
