Linear voltage regulators are a type of PMIC (Power Management Integrated Circuit) used to ensure that a particular power module is outputting the exact voltage of current needed. The LE33ABZ linear voltage regulator is a polysilicon thin-film transistors (TFT) technology that is Ideal for low noise and low voltage applications, such as portable devices, displays, and automotive.

The LE33ABZ is capable of providing output voltages as low as 0.8V, with a load current up to 75mA, and excellent output noise characteristics. It supports both adjustable and fixed output voltage configurations, enabling designers to pick and optimise their system voltages as needed.

The LE33ABZ features an integrated current limit functionality that helps protect against overload and short circuits. With a simple current limit resistor (RCL) connected at each device pin, the user can increase the maximum current handling capability to approximately 90mA. This provides designers with a level of protection that also helps extend system lifetime.

The LE33ABZ uses a high-performance, low-dropout regulator architecture that helps minimise power consumption while providing high-quality output power. It also features a wide operating voltage range from 2.5V to 15V, enabling the user to power the system from a range of sources, such as batteries, DC sources and AC adapters.

The LE33ABZ also has a number of added features such as an enable pin that can be used for powering up/down the regulator. It also has a specialized startup sequence that helps reduce system startup time by providing a regulated output at a lower voltage level than the input voltage. This feature helps reduce abuse of the regulator during startup and helps provide stable system performance.

The LE33ABZ is ideal for a variety of different applications, such as automotive, portable devices, displays, digital cameras and gaming devices. The high output current and low voltage capability allow it to be used in a wide variety of systems, helping extend system lifetime, reduce noise and save power.

The working principle of the LE33ABZ is relatively straightforward. It uses a circuit consisting of an error amplifier, a reference voltage and a logic block. The error amplifier compares the output voltage with a reference voltage, and then adjusts the gate voltage of the pass transistor accordingly. This controls the output voltage, ensuring that the desired level is maintained. The reference voltage is typically fixed for a given part number, however, adjustable versions are available.

The LE33ABZ is a reliable and robust linear voltage regulator device. It offers a wide range of features and features that enable designers to pick and optimise their system requirements. The low dropout regulator architecture and high output current help reduce power consumption, extend system lifetime and reduce noise. The integrated current limit also helps protect against overload and short circuit conditions, making it an ideal choice for a variety of applications.
