The LE33CZ-AP is a series of high-performance, low-dropout linear voltage regulators (LDOs) manufactured by Texas Instruments. This series is the perfect choice for applications where great accuracy, low output noise, and high current capability are important characteristics. It offers up to 4A peak output current, a dropout voltage of only 800mV, and a wide input voltage range of 1.2V to 6.5V. The LE33CZ-AP can provide a stable output voltage from 2.5V to 6.0V. It is capable of powering a variety of electronics, from batteries and computer parts, to high-performance memory cards and DVDs.

The LE33CZ-AP series features an internal reverse current protection and a thermal shutdown circuit to protect against overheating. The device also features current limiting, which keeps the current limited under the programmed current limit threshold, and over-voltage protection, which prevents the output voltage from rising over the maximum “ON” voltage to an unacceptable level. This protection against over-voltage can help protect circuits connected to the output of the LE33CZ-AP.

The LE33CZ-AP can be easily configured to meet specific requirements with little to no external components. Internal compensation features a low-ESR ceramic output capacitor, a power supply rejection of up to 78dB, and an internal BIAS voltage generator for Vout setting. An innovative control loop eliminates the need for any external components, even with high load inrush current or prolonged high current load operation.

The LE33CZ-AP features an adjustable output current up to 4A, a low dropout voltage of 800mV, and a wide operating temperature range of –40°C to +85°C. This ensures the highest stability, accuracy and reliability in all environmental conditions. The LE33CZ-AP is also designed to meet the power distribution requirements of mobile applications, with step-down converters and DC/DC controllers.

The LE33CZ-AP offers excellent load regulation, input/output current and thermal stability. Equipped with a dual voltage comparator as well as an internal circuit with open-loop voltage gain optimization, it provides a stable output and excellent transient response over the entire load range. The device is capable of withstanding up to 12V transient spikes and is designed to withstand up to 6V of output glitch at full load. These features, along with its low thermal resistance, make the LE33CZ-AP the ideal choice for powering sensitive loads, such as cellular phones, PDAs and other mobile devices.

In summary, the LE33CZ-AP is a high performance low drop-out linear voltage regulator that offers reliable performance, a wide operating temperature range, adjustable current output up to 4A, reverse current protection and thermal shutdown, and high power supply rejection. The device’s wide input voltage range and low power consumption make it a great choice for applications that require a high level of reliable power delivery in a small space. Additionally, the LE33CZ-AP is a cost-effective solution for designers looking for a robust, reliable and low-dropout voltage regulator for their systems.
