NCP161ASN330T1G Description

Short technical summary and product information.

The NCP161ASN330T1G is a linear voltage regulator (LDO) from On Semiconductor, providing a fixed 3.3V output with a maximum output current of 450mA. It operates from an input voltage range of 1.9V to 5.5V, making it suitable for low-power battery-powered applications. The regulator features a typical quiescent current of 18µA and a standby current of only 0.1µA, maximizing efficiency in portable devices.

 

With a dropout voltage of 150mV typical at 450mA, the NCP161 maintains regulation even with small input-to-output voltage differentials. Output accuracy is ±2% over load and temperature. The device is available in a SOT-23-5 package, which is suitable for compact circuit designs. The NCP161 series also offers other fixed voltage options from 1.8V to 5.14V, though this specific variant is configured for 3.3V output.
