NCP511SN25T1 Description

The NCP511SN25T1 is a linear voltage regulator designed for applications requiring a fixed output voltage of 2.5V and a maximum output current of 150mA. Manufactured by onsemi, this regulator is part of the Power Management Integrated Circuit (PMIC) category. It features a maximum input voltage of 6V and is designed with a single regulator output configuration. The device is optimized for low power consumption, with a maximum supply current of 100 µA and a quiescent current (Iq) of 40 µA. The NCP511SN25T1 is housed in a 5TSOP package and is available in a Surface Mount configuration, making it suitable for compact and space-constrained designs. Despite its small size, it offers robust protection features, including over-current and over-temperature protection, ensuring reliable operation under various conditions. The regulator also features an enable control feature, allowing for dynamic control of the output voltage. With a maximum dropout voltage of 0.2V at 100mA, the NCP511SN25T1 ensures efficient power delivery even at low input-to-output voltage differentials. The device has a Power Supply Rejection Ratio (PSRR) of 50dB at 1kHz, which helps in maintaining a stable output voltage in the presence of input voltage fluctuations. The NCP511SN25T1 is REACH unaffected and has a Moisture Sensitivity Level (MSL) of 1, indicating it is suitable for unlimited exposure to moisture, making it ideal for a wide range of manufacturing processes. The product is currently marked as obsolete, but it remains a viable option for legacy systems and specific applications where its unique features are required.
