Overview

Description

The LD39100PUR is a linear voltage regulator integrated circuit designed for low-dropout applications where efficient voltage regulation is required. It provides a stable output voltage with low noise and high power supply rejection ratio (PSRR), making it suitable for sensitive electronic components. The device typically offers an output current capability of up to 1A, with a dropout voltage as low as 200mV under specific conditions, which helps in energy-efficient operation by minimizing the voltage difference between input and output.
The LD39100PUR includes features like thermal protection, current limitation, and an enable pin for easy on/off control, enhancing its reliability and versatility in various applications. It is commonly used in consumer electronics, industrial equipment, and automotive systems to power microcontrollers, sensors, and other low-voltage circuits.
Packaged in a compact form factor, it often comes in a SOT-223, DPAK, or similar surface-mount package, making it a good choice for applications where space is a constraint. The regulator's design emphasizes low quiescent current, which is beneficial for battery-powered devices to extend operational life.

Features

The LD39100PUR is a low-dropout (LDO) voltage regulator. Key features include:
1. Output Current: Capable of delivering up to 1A of output current.
2. Low Dropout Voltage: Typically around 200mV at full load, improving efficiency.
3. Input Voltage Range: Operates within a wide input voltage range, typically 1.5V to 5.5V.
4. High PSRR: Provides high Power Supply Rejection Ratio, ensuring stable operation with minimal noise.
5. Low Quiescent Current: Offers low quiescent current, which is beneficial for battery-powered applications.
6. Protection Features: Includes thermal shutdown and current limit protection to prevent damage due to overheating or overloading.
7. Stability: Stable operation with low ESR capacitors, enhancing reliability.
8. Package: Available in a compact package size, often suitable for space-constrained applications.
These features make the LD39100PUR suitable for applications requiring efficient power management and stable voltage regulation, such as portable devices, telecommunications equipment, and consumer electronics.

Package

The LD39100PUR is a low-dropout (LDO) voltage regulator from STMicroelectronics, and it is typically available in a DFN (Dual Flat No-lead) package type, specifically DFN-6 (also known as a 6-lead DFN), which is compact and suitable for space-constrained applications.

Pinout

The LD39100PUR is a low-dropout linear voltage regulator. It typically comes in an SOT-89-5L package and has 5 pins. Here is a concise overview of its pin functions:
1. Pin 1 (IN): Input voltage pin where the unregulated voltage is supplied.
2. Pin 2 (GND): Ground pin, serves as the common ground for the input and output.
3. Pin 3 (EN): Enable pin used to turn the regulator on or off. High level enables the regulator, and low level disables it.
4. Pin 4 (NC): No Connection. This pin is not internally connected and can be left floating.
5. Pin 5 (OUT): Output voltage pin where the regulated voltage is provided.
This regulator is designed to provide a stable output with low dropout voltage and high power supply rejection ratio, making it suitable for a variety of applications where space and efficiency are critical.
