The LP38690DTX-5.0/NOPB is a low-power, low-noise, low-dropout linear regulator with a low quiescent current. It is ideal for applications that need to operate with a wide input voltage range and require low noise voltage regulation. It is a member of the family of Texas Instruments\' low-voltage, low-dropout linear regulators.

The LP38690DTX-5.0/NOPB is designed to regulate an output voltage of 5V with an input voltage of up to 18V. It has an adjustable output voltage of 4.75V to 5.25V. The regulator delivers up to 100mA of continuous output current and can withstand short duration overloads of up to 130mA. It is available in a tiny 8-pin LLP (leadless low profile) package with a low profile of 1.2mm and small footprint.

The regulator is available in two versions, the low-dropout version (LP38690DTX-5.0/NOPB) and the low-noise version (LP38690ETX-5.0/NOPB). The low-dropout version has a dropout voltage of 1.2V typical, while the low-noise version has a dropout voltage of 1.5V typical.

The LP38690DTX-5.0/NOPB regulator uses a proprietary, advanced low-quiescent current design to increase efficiency and extend battery life. It also utilizes a proprietary overcurrent protection circuit to protect against loading faults. Additionally, it is designed with overvoltage protection that limits the output voltage to 6.5V under abusive conditions.

The LP38690DTX-5.0/NOPB is well suited for applications with moderate power requirements, such as those in handheld devices, portable audio players and various other small battery-powered products. It can also be used in automotive systems and applications where high efficiency, low quiescent current, and low noise are required.

The working principle of the LP38690DTX-5.0/NOPB is based on a typical linear regulator design. It consists of an input stage, a feedback stage, an error amplifier, and a series pass transistor. The input stage is typically a reference voltage source, while the feedback stage is typically a resistive divider. The error amplifier compares the output voltage with a reference voltage and produces an error voltage. The series pass transistor is then used to adjust the output voltage based on the error voltage. This ensures that the output voltage always remains within a specified tolerance.

Overall, the LP38690DTX-5.0/NOPB is a low-power, low-noise, low-dropout linear regulator that is well suited for applications with moderate power requirements. It is available in two versions, the low-dropout version and the low-noise version, which makes it versatile for a variety of applications. It\'s low quiescent current design and overvoltage protection makes it an ideal choice for a variety of products including handheld devices and portable audio players.
