NCP186AMX330TAG

The NCP186AMX330TAG is a fast transient response CMOS low dropout (LDO) linear voltage regulator with active discharge in 8 pin XDFN package. This very Low dropout regulator provides up to 1A of load current and maintains excellent output voltage accuracy of 1% in -40°C to 85°C range. The operating input voltage range from 1.8V up to 5.5V makes this device suitable for Li-ion battery powered products as well as post regulation applications. The NCP186 is fully protected against overheating and output short circuit. The small XDFN package makes the device especially suitable for space constrained applications. It also features extended battery life and saves PCB space and system cost.

• Fixed output voltage of 3.3V
• Provides design flexibility
• Low quiescent current of 90µA extends battery life and standby current of 0.1µA at VEN = 0V
• Good for noise sensitive circuits
• Very low dropout of 95mV at Iout = 1A
• High PSRR of 75dB at 1KHz and output noise of 48µVRMS at f = 10Hz to 100KHz
• Built-in soft start circuit to suppress inrush current and over current protection
• Load regulation of 0.7mV (IOUT=1 to 1000mA) & line regulation of 0.002%/V (VIN=VOUT_NOM + 0.5 to 5V)
• Stable with small 1µF ceramic capacitors
• Thermal shutdown and current limit protections protects product and system from damage
