The LP38690DT-5.0/NOPB is a high-performance, low-dropout voltage regulator designed and manufactured by Texas Instruments. This reliable linear regulator provides a fixed output voltage of 5.0V with an output current capability of up to 1A, making it an excellent choice for a wide range of applications requiring a stable power supply.

Key Features

• Output Voltage: Precisely regulated 5.0V output, ideal for powering 5V logic and microcontrollers in embedded systems.
• High Current Output: Capable of delivering up to 1A of continuous output current to meet the needs of power-hungry devices.
• Low Dropout Voltage: With a typical dropout voltage of just 1.3V at full load, it ensures efficient operation even when the input voltage is close to the output voltage.
• Stable with Low ESR Capacitors: The regulator is stable with ceramic output capacitors, which have lower equivalent series resistance (ESR) than tantalum or aluminum electrolytic capacitors.
• Thermal Protection: Integrated thermal shutdown protection prevents damage from overheating, enhancing the longevity and reliability of both the regulator and the overall system.
• Overcurrent Protection: Built-in current limit protection safeguards the device and the load from excessive current draw.
• No Pullback Under Thermal Shutdown: The output remains high-impedance when the device is in thermal shutdown, preventing the regulator from pulling down the bus.

Applications

The LP38690DT-5.0/NOPB is versatile and can be used in a variety of electronic systems, including:

• Consumer Electronics
• Automotive Infotainment and Body Control Modules
• Industrial Control Systems
• Telecommunications Infrastructure
• Portable and Battery-Powered Devices

Package and Availability

The device is available in a TO-252 (DPAK) surface-mount package, which is suitable for automated assembly processes and helps to save board space. The 'NOPB' suffix indicates that this device is provided in an environmentally friendly, RoHS-compliant package that is free of lead (Pb).

With Texas Instruments' reputation for quality and performance, the LP38690DT-5.0/NOPB is a robust and dependable choice for designers looking to incorporate a stable and efficient voltage regulator into their electronic designs.
