Description and Introduction

1.0 A Low-Dropout Positive Fixed and Adjustable Voltage Regulators # Introduction to the NCP1117ST33T3 Voltage Regulator  

The **NCP1117ST33T3** is a low-dropout (LDO) linear voltage regulator designed to provide a stable and reliable **3.3V output** from a higher input voltage. Manufactured by ON Semiconductor, this component is widely used in applications requiring precise voltage regulation, such as embedded systems, consumer electronics, and industrial controls.  

With a **maximum output current of 1A** and a low dropout voltage (typically **1.2V at full load**), the NCP1117ST33T3 ensures efficient power conversion while minimizing heat dissipation. It features built-in **overcurrent protection, thermal shutdown**, and **short-circuit protection**, enhancing system reliability under demanding conditions.  

Available in a **SOT-223 package**, the regulator is compact and suitable for space-constrained designs. Its **fixed 3.3V output** eliminates the need for external resistors, simplifying circuit implementation. Additionally, the NCP1117ST33T3 maintains stable performance across a **wide input voltage range (up to 20V)**, making it versatile for various power supply configurations.  

Engineers favor this regulator for its **low quiescent current**, high accuracy (±2%), and robustness in harsh environments. Whether used in battery-powered devices or noise-sensitive analog circuits, the NCP1117ST33T3 delivers consistent performance with minimal external components.
