CHL8328-01CRT is a special purpose voltage regulator designed for automotive, industrial and consumer applications. Produced by ChangLin, this device is notable for its advanced ultra-low dropout (ULDO) technology, offering high accuracy and low dropout characteristics. The CHL8328-01CRT is a feature-rich, single-stage voltage regulator that virtually eliminates the need for an external Schottky diode or load switch and connects directly to the input voltage source. It is ideal for systems with a limited board space and where the load current requires a high level of regulation accuracy, such as motor control, car navigation, and audio amplifier applications.

The CHL8328-01CRT features an integrated state-of-the-art quasi resistor (QR) current sense that removes the need for a resistor to adjust the loop gain. This QR current-sense solution enables lower cost and more reliable output current sensing at high currents, while maintaining excellent loop gain. The CHL8328-01CRT is capable of delivering up to 2.5A of continuous regulated current and up to 5A of peak (transient) current.

In terms of performance, the CHL8328-01CRT offers superior stability and linear regulation, in line with automotive industry standards. Its wide input voltage range of 3V~35V makes it suitable for both single and dual-channel applications, and it also delivers adjustable output voltages from 0.6V~30V. To protect against over-current conditions, the CHL8328-01CRT is equipped with an adjustable soft-start and over-current limit function, allowing the output to be precisely controlled.

The CHL8328-01CRT uses the latest in ULDO technology, allowing it to achieve a low dropout voltage of 0.24V at full load, while still providing superior accuracy and line regulation. It also features a low-noise fast transient response, making it suitable for demanding audio and video applications. Additionally, the device is multiplexed, allowing it to be configured to accept input from either a single supply or from two separate supplies.

CHL8328-01CRT is an ideal voltage regulator for applications that require high efficiency, small board area and excellent regulation accuracy. Its ULDO technology ensures that the device operates efficiently and with minimal power consumption, while its adjustable high-current limit and fast transient response guarantee that it is capable of handling transient load changes. The CHL8328-01CRT is especially suitable for automotive, industrial and consumer applications and is fully compliant with the AEC-Q100 standard.
