The LT1374IR-5SYNC#PBF is a three-terminal, low dropout (LDO) linear regulator, featuring typical quiescent currents of only 50 µA over the specified input voltage and output voltage ranges. This is ideal for a wide range of applications, such as cellular phones, laptop computers, PDAs, and other high-precision, low-power portable systems. The LT1374IR-5SYNC#PBF is recommended for use as a post-processing power supply or as a backup or a power supply in a wireless base station.

This device belongs to PMIC - Voltage Regulators - DC DC Switching Regulators. PMIC stands for power management integrated circuits, a type of circuit that is used to create, control and store energy for electronic products. Voltage regulators are usually responsible for controlling the input and output voltages in a particular circuit, such as DC-DC switching regulators. These circuits convert a steady supply of DC from an existing power source into variable voltage, which the circuit can then control. The LT1374IR-5SYNC#PBF is a DC-DC switching regulator, meaning it can switch between a steady supply of DC power and variable output voltage.

The LT1374IR-5SYNC#PBF uses a synchronous step-down DC/DC converter in order to achieve very low dropout and low output ripple, making it suitable for a wide range of applications. The output voltage is adjustable and it can be set to the desired voltage level between 1.8V and 5.5V. It has a wide input range of 4V to 16V making it suitable for a wide range of operating conditions. It also features precision current-limit protection and thermal shutdown protection. As a result, it is capable of maintaining precise voltage control even when conditions are not optimal.

In addition to its low dropout and low output ripple features, the LT1374IR-5SYNC#PBF also has high efficiency and low noise output over the full operating range. The device incorporates a frequency-synchronized, variable frequency control, which minimizes the output ripple. The device also has a wide range of input, output, and switching frequencies, so it can be adjusted to match the specific requirements of the application.

The LT1374IR-5SYNC#PBF is ideal for portable and low-power applications where low ripple, low dropout and precise regulation are crucial for optimal performance. Typical applications include cellular phones, digital cameras, PDAs and other portable systems that require power under low supply conditions. This device can also be used in wireless base stations and other high-precision, low-power systems, as well as general-purpose and automotive systems.
