NCP140BMXD330TCG

NCP140BMXD330TCG Description

The NCP140BMXD330TCG is a fixed output linear regulator designed for applications requiring a stable 3.3V supply with a maximum output current of 150mA. Manufactured by onsemi, this device is part of the Power Management Integrated Circuits (PMIC) category and is housed in a compact 4x4 DFN package, making it suitable for space-constrained designs. Despite being marked as obsolete, the NCP140BMXD330TCG continues to offer reliable performance with a maximum input voltage of 5.5V and a dropout voltage of only 0.22V at 150mA. This low dropout voltage ensures efficient power delivery even at low input-to-output voltage differentials. The regulator features a quiescent current of 75 µA, contributing to its energy-efficient operation. Additionally, it offers a high power supply rejection ratio (PSRR) ranging from 62dB at 100Hz to 55dB at 1kHz, which helps in minimizing noise and ripple in the output voltage. The NCP140BMXD330TCG also includes an enable control feature and over-temperature protection, enhancing its versatility and reliability in various electronic systems.
