NCP703 300 mA, Ultra-Low Quiescent Current, I 12 A, Ultra-Low Q Noise, LDO Voltage Regulator Noise sensitive RF applications such as Power Amplifiers in satellite radios, infotainment equipment, and precision www.onsemi.com instrumentation require very clean power supplies. The NCP703 is 300 mA LDO that provides the engineer with a very stable, accurate voltage with ultra low noise and very high Power Supply Rejection 5 Ratio (PSRR) suitable for RF applications. The device doesnt require 1 1 any additional noise bypass capacitor to achieve ultralow noise TSOP5 XDFN6 performance. In order to optimize performance for battery operated SN SUFFIX MX SUFFIX portable applications, the NCP703 employs dynamic Iq management CASE 483 CASE 711AE for ultralow quiescent current consumption at lightload conditions and great dynamic performance.

A small 1 F ceramic capacitor is needed from this pin to ground to assure stability. 2 4 N/C Not connected. 3 2 GND Power supply ground. Connected to the die through the lead frame. Soldered to the copper plane allows for effective heat dissipation. 4 3 EN Enable pin. Driving EN over 0.9 V turns on the regulator. Driving EN below 0.4 V puts the regu- lator into shutdown mode. 5 N/C Not connected. This pin can be tied to ground to improve thermal dissipation. 6 1 IN Input pin. A small capacitor is needed from this pin to ground to assure stability. Table 2.
