NCP133AMX130TCG

The NCP133AMX130TCG is a 500 mA Very Low Dropout (VLDO) linear voltage regulator designed for noise-sensitive applications. It features an NMOS pass transistor and a separate bias supply voltage (V BIAS) for stable and accurate output.

Key electrical specifications include an input voltage range of 0.8 V to 5.5 V and a fixed output voltage of 1.3 V. The device offers an ultra-low dropout voltage, typically 140 mV at 500 mA, and a maximum dropout of 0.25V at 500mA. It provides ±1.5% accuracy over temperature and 0.5% accuracy at 25°C. The regulator operates with very low quiescent current, typically 80 µA, and even lower in disable mode (0.5 µA).

Designed for space-constrained applications, the NCP133AMX130TCG is available in a 1.2 mm x 1.2 mm XDFN6 package. It includes features such as over current, over temperature, and under voltage lockout (UVLO) protection. The device is stable with a 2.2 µF ceramic capacitor and has a logic-level enable input for ON/OFF control.

Typical applications include battery-powered equipment, smartphones, tablets, cameras, DVRs, STBs, and camcorders where stable, low-noise power is critical.
