The NCP703SN18T1G from ON Semiconductor is a 300 mA, ultra-low quiescent current, ultra-low noise LDO voltage regulator. It is designed for noise-sensitive RF applications requiring clean power supplies, such as satellite radios and precision instrumentation. The device operates with an input voltage range of 2.0 V to 5.5 V and provides a fixed 1.8 V output voltage with ±2% accuracy over line, load, and temperature.
Key features include ultra-low noise performance of 13 µVRMS from 100 Hz to 100 kHz, a very low dropout voltage of 180 mV typical at 300 mA, and high Power Supply Rejection Ratio (PSRR) of 68 dB at 1 kHz. It also incorporates internal soft-start to limit inrush current and protections for over current and over temperature. The NCP703SN18T1G is stable with a 1 µF ceramic output capacitor and is available in a 5-TSOP package suitable for surface mounting.
Typical applications include PDAs, mobile phones, GPS, smartphones, wireless handsets, wireless LAN, Bluetooth, Zigbee, portable medical equipment, and other battery-powered devices. The device also features active output discharge for fast turn-off.
