L4938ND013TR Integrated Circuits (ICs)

PMIC - Voltage Regulators - Linear

The L4938ND013TR is a low-dropout voltage regulator designed specifically for portable electronic devices. It is a linear voltage regulator with extremely low dropout voltage and low power consumption, making it suitable for high current applications in a compact package. The L4938ND013TR is available in a TO-220 package or in a micro SMD package for space-constrained designs. It has a wide input voltage range of 2.5 V to 15 V, and is capable of providing a regulated output voltage from 0.8 V to 11 V.

The main working principle of a linear voltage regulator is to maintain a constant output voltage regardless of the input voltage. To achieve this, the regulator uses a series of transistors that act as resistors to control the amount of current passing through the circuit. As the input voltage increases, the transistors limit the amount of current passing through the regulated output.

The L4938ND013TR is used in a variety of portable electronic devices such as cell phones, PDAs, digital cameras, and USB devices. It is also used in a variety of applications such as motor control, lighting, and audio amplification. It can be used as a power supply for low power embedded systems, and it can also be used to provide a regulated voltage for RF applications.

The L4938ND013TR can provide an output current of up to 3 A with a maximum dropout voltage of 0.4 V. It has both short-circuit and thermal protection, and it comes with a thermal shutdown circuit with a temperature-dependent current foldback behavior. The device also has a low-noise operation and offers a high ripple rejection ratio for clean and stable power supply.

The L4938ND013TR is an ideal choice for portable and space-constrained applications that require high current and low dropout voltage. It is also suitable for a variety of other applications where reliable and clean power is required.
