NCP565MN12T2G

NCP565MN12T2G Description

The NCP565MN12T2G from onsemi is a high-performance, fixed-output linear voltage regulator designed to deliver a stable 1.2V output at up to 1.5A of continuous current. With a wide input voltage range of up to 9V, this regulator is optimized for low-dropout operation, making it suitable for applications requiring precise voltage regulation under varying load conditions. Packaged in a compact 6DFN surface-mount form factor, it is ideal for space-constrained designs. The device features over-current and over-temperature protection, ensuring robust operation in demanding environments. Although marked as Obsolete, it remains a reliable choice for legacy systems due to its high PSRR (85dB @ 120Hz) and low quiescent current (3 mA), which minimize power dissipation and noise.
