Overview

Description

The TLE4267G is a 5V low-dropout (LDO) voltage regulator commonly used in automotive and industrial applications. It is designed to provide a stable and regulated output voltage from a wide input voltage range, typically from 5.5V to 45V, making it suitable for use in environments with varying power supply conditions. The "G" in its designation often refers to the package type, with this component typically available in a TO-263 surface-mount package.
Key features of the TLE4267G include a high accuracy output voltage, low quiescent current, and a robust protection scheme that includes overtemperature shutdown and short-circuit protection. It also has an enable function, allowing it to be turned on or off via a control signal, which is useful for power management in complex systems.
The LDO's low dropout voltage, typically around 250mV at 100mA, ensures efficient operation even as the input voltage approaches the output voltage level. This makes the TLE4267G ideal for applications requiring high efficiency and reliability.

Equivalent

The TLE4267G is a low-dropout voltage regulator commonly used in automotive applications. Equivalent products could include the LM2940, MIC29300, and the NCP1117, among others. These alternatives offer similar functionalities, like low dropout voltage and over-current protection. However, while substituting, ensure the electrical specifications, package type, and thermal performance match your requirements. Always consult the datasheets for compatibility.

Features

The TLE4267G is a voltage regulator designed for automotive applications. It provides a fixed output voltage of 5V with a maximum output current of 450 mA. Key features include:
1. Low Dropout Voltage: Ensures efficient operation by maintaining regulation at low input-to-output voltage differentials.

2. Overtemperature Protection: Prevents damage by shutting down the device if it overheats.
3. Output Current Limitation: Protects against excessive current by limiting the output.
4. Reverse Polarity Protection: Safeguards the device from damage due to incorrect battery connection.
5. Wide Supply Voltage Range: Suitable for various automotive electrical systems with an input voltage range typically from 5.5V to 45V.
6. Very Low Current Consumption: Ensures minimal power draw when in standby mode.
7. Suitable for Automotive Environments: Designed to meet the rigorous demands of automotive applications, including load dump protection.
The TLE4267G is typically used in power supply circuits for microcontrollers and other digital components in automotive electronic systems.

Pinout

The TLE4267G is a low-dropout (LDO) voltage regulator designed for automotive applications. It typically comes in a PG-TO263-5 package.
Here is a brief description of its pin configuration and functions:
1. Pin 1 (I - Input): This pin is connected to the input voltage source that needs to be regulated.
2. Pin 2 (GND - Ground): This is the ground pin and serves as the common ground for the input and output.
3. Pin 3 (Q - Output): The regulated output voltage is provided at this pin.
4. Pin 4 (ADJ - Adjust): This pin is used to set the output voltage externally through a resistor divider network.
5. Pin 5 (EN - Enable): This pin enables the device when a high signal is applied; a low signal puts the device in a low-power shutdown mode.
The TLE4267G is known for its robustness, overvoltage protection, and low quiescent current, making it suitable for automotive electronics where stable voltage is necessary despite varying input conditions.
