The TL751L05CDE4 is a voltage regulator specifically designed for use in cost-sensitive and space-restricted applications. This voltage regulator is particularly suited for the mobile markets, such as those in mobile phones and handheld devices. It operates from a wide input voltage range from 3 V to 20 V and can provide up to 250 mA of output current when in use.

This voltage regulator is designed using a low dropout, linear regulator architecture. This architecture utilizes an input bypass capacitor connected to the input voltage pin to filter out the high-frequency noise present on the input power supply line. This reduces the amount of transient noise present on the input line and thereby reduces the amount of radiated emissions from the regulator.

The TL751L05CDE4 utilizes a common-mode feedback architecture. This architecture provides better ac line regulation compared to standard linear regulators. This is due to the fact that the regulator is operating within its common-mode operating region, where the input voltage is always close to the output voltage. In addition, the common-mode feedback architecture also provides better transient response and improved line rejection, since the line rejection is improved by the fact that the line voltage is always in the same voltage range as the output voltage.

The TL751L05CDE4 regulator has an internal power-on-reset comparator circuit that ensures proper and safe start-up of the regulator. This circuit monitors the input voltage and will activate the reset signal if the input voltage is outside of the specified bounds. This ensures that the output voltage is not inadvertently allowed to drift outside of the specified range.

The TL751L05CDE4 regulator includes an internal short-circuit protection circuit. This circuit monitors the output voltage under load conditions. If the voltage drops below the specified threshold, the regulator will disable the output, which prevents any further drop in the output voltage.

The TL751L05CDE4 is ideal for applications where cost and space are critical factors. This voltage regulator is designed to operate from a wide input voltage range, allowing it to be used in many different applications. In addition, the internal circuitry of the regulator provides both protection against overloads and increases the regulator’s ac line regulation. This makes the TL751L05CDE4 an ideal solution for cost-sensitive and space-restricted applications.
