Description and Introduction

150 mA CMOS Low Iq Low-Dropout Voltage Regulator The **NCP561SN25T1** is a highly efficient, low-dropout (LDO) linear voltage regulator designed for applications requiring stable and precise power delivery. Manufactured by ON Semiconductor, this component provides a fixed output voltage of **2.5V** with a maximum output current of **150mA**, making it suitable for low-power embedded systems, portable electronics, and IoT devices.  

Featuring a low dropout voltage of **160mV at 150mA**, the NCP561SN25T1 ensures optimal performance even when the input voltage is close to the output level. Its ultra-low quiescent current of **1.1µA** enhances energy efficiency, extending battery life in power-sensitive applications. Additionally, the regulator includes built-in protection features such as **thermal shutdown and current limiting**, safeguarding against potential damage from overheating or excessive load conditions.  

The compact **SOT-23-5** package allows for space-efficient PCB designs, making it ideal for compact and portable electronics. With its stable operation across a wide temperature range (**-40°C to +125°C**) and low output noise, the NCP561SN25T1 is a reliable choice for precision analog and digital circuits.  

Engineers and designers seeking a robust, low-power voltage regulator with minimal footprint will find the NCP561SN25T1 a dependable solution for their power management needs.
