Description and Introduction

The Linear ICs Three-Terminal Low Current Positive Voltage Regulators The 78L05AC is a linear voltage regulator manufactured by Texas Instruments (TI). It provides a fixed output voltage of 5V and is designed for low-power applications. Key specifications include:

- **Output Voltage:** 5V ±4% (typical)
- **Output Current:** Up to 100mA
- **Input Voltage Range:** 7V to 20V
- **Dropout Voltage:** 1.7V (typical) at 40mA
- **Operating Temperature Range:** 0°C to 125°C
- **Package:** TO-92, SOT-89, or SOIC
- **Internal Thermal Overload Protection:** Yes
- **Internal Short-Circuit Current Limiting:** Yes
- **Low Quiescent Current:** Typically 5mA

This regulator is commonly used in applications requiring a stable 5V supply, such as in small electronic devices and circuits.

Description and Introduction

The Linear ICs Three-Terminal Low Current Positive Voltage Regulators The **78L05AC** from Texas Instruments is a widely used linear voltage regulator designed to provide a stable **+5V DC output** from a higher input voltage. As part of the **78Lxx series**, this low-current regulator is ideal for applications requiring reliable power regulation with minimal external components.  

With a maximum output current of **100mA**, the 78L05AC is suitable for low-power circuits, such as microcontroller systems, sensor modules, and small analog devices. It features built-in thermal overload protection and short-circuit prevention, ensuring safe operation under varying load conditions. The device operates within an input voltage range of **7V to 20V**, making it compatible with common power supplies.  

Housed in a compact **TO-92 package**, the 78L05AC is easy to integrate into breadboards and PCBs. Its simplicity and efficiency make it a preferred choice for hobbyists and engineers alike. Unlike switching regulators, this linear regulator provides low-noise output, which is advantageous for sensitive analog circuits.  

Key specifications include a **±4% output voltage tolerance** and a dropout voltage of around **2V**, ensuring stable performance even with fluctuating inputs. Whether for prototyping or production, the 78L05AC remains a dependable solution for basic voltage regulation needs.
