The UA78L series of fixed-voltage linear regulators is designed for a wide range of applications. The UA78L series can be used for on-card regulation to eliminate the noise and distribution problems associated with single-point regulation. The UA78L can also be used with power-pass elements to make high-current voltage regulators. The UA78L series regulators can deliver up to 100 mA of output current. Additionally, the UA78L does not need an external capacitor for stable operation across the load current range. The internal current-limiting and thermal-shutdown features of these regulators help protect the device from overload.

For the legacy chip, the UA78L00C and UA78L00AC series are characterized for the junction temperature range of 0°C to +125°C and the UA78L05AI device is characterized for the operating junction temperature range of -40°C to +125°C.

For the new chip, the UA78L series is characterized by the junction temperature range of -40°C to +125°C.

Texas Instruments UA78L05ACLPM's Category-Low Drop Out(LDO) Regulators

LDO stands for Low Dropout Regulator, which is a low-power low-dropout linear voltage regulator. It automatically adjusts the voltage occupied by the transistor or field-effect transistor in the linear region through internal negative feedback to obtain a stable output voltage drop from the input voltage.

Under the condition of changes in input voltage or load current, LDO can still maintain a stable output voltage; it has extremely low inherent noise and a high power supply rejection ratio (PSRR). More details: Introduction and Common Types of Linear Low Dropout Voltage Regulator Chips.
 

Manufacturer of UA78L05ACLPM - Texas Instruments 

TI is an international semiconductor company in the United States, headquartered in Dallas, Texas. The company was established in 1930 and has more than 100 offices worldwide, with more than 43,000 employees in the United States, Europe, Asia, and Latin America. TI is a global leading semiconductor manufacturer and has an important influence on multiple fields such as computers, communications, industrial control, and healthcare.

The history of Texas Instruments can be traced back to 1930 when inventor and engineer James Korklewski established Geophysical Service Incorporation to create a sales company for electronic equipment. In 1941, TI was restructured into an independent company and began to engage in scientific and technological research and development and semiconductor production. TI first introduced transistors in the 1950s. In the 1960s, the company began to engage in the integrated circuit industry and produced the world's first single-chip microcomputer in 1971, which greatly changed the development model of the computer industry.
 
Texas Instruments products include analog integrated circuits, digital signal processors, single-chip microcontrollers, power management devices, chip solutions, and radio frequency controllers. These electrical components are sold to the aerospace, defense, industrial, personal electronics, and communications markets. They cover portable audio devices, high-definition televisions, car navigation, mobile phones, automotive signal processing, industrial control equipment, and security protection.

Texas Instruments' globalization strategy relies on an understanding of cross-cultural, language, and technology. In the past few decades, TI has expanded its business globally. It is very popular in the Asian market. The company has opened offices and factories in China, Southeast Asia, and India, aiming to expand its market share and improve competitiveness. More detail: Analog Semiconductor Leader – TI (Texas Instruments)
