The LP5952TL-1.5EV is a voltage regulator that belongs to the Evaluation Boards - Linear Voltage Regulators category of components. This voltage regulator is designed for use in applications ranging from battery-powered applications to higher current systems. The LP5952TL-1.5EV voltage regulator provides up to 1.5A of output current with only a few external components, offering features and functionalities that are not available from other devices.

The main features of the LP5952TL-1.5EV voltage regulator are its high efficiency, low-noise operation, and improved thermal performance. These features make it the ideal choice for applications that require long life, low output voltage noise, and high efficiency. Additionally, the LP5952TL-1.5EV has excellent transient response and stability over temperature and load.

The LP5952TL-1.5EV is a buck regulator that operates with an input voltage of between 2V and 24V. It is designed to provide a stable, regulated output voltage of between 0.8V and 20V with either a single-ended control range or different dual-ended control ranges. The output voltage can be configured to 0.1V or 1.25V increments. The output current can be limited up to 1.5A with external sensing resistors.

The LP5952TL-1.5EV features two on-chip voltage reference options, a 1x or 800mV reference. The reference has an accuracy range of between 0.7V and 5.5V with any given temperature range. The voltage reference can be programmed either through the PMBus commands or through a register. The PMBus commands provide a range of customizable parameters for regulating the output voltage.

The LP5952TL-1.5EV performs the regulation by comparing the feedback signal to the reference voltage. The adjustable current limit can be programmed to maintain the typical output current when the voltage output exceeds either the overload or temperature limit. The status of the voltage regulator can be monitored through the built-in sense pin, which provides a fast and accurate indication of the input and output voltages and temperature. The status can be viewed through the onboard feedback LEDs.

The LP5952TL-1.5EV includes integrated short-circuit, thermal shutdown, and over-voltage protection. The over-voltage protection is designed to prevent the output voltage from exceeding a programmed maximum output voltage, while the short-circuit protection shuts down the regulator in the event of a short-circuit. The thermal shutdown maintains the temperature of the device by shutting down the output voltage if the temperature exceeds a certain set point.

The LP5952TL-1.5EV is packaged in a 14-pin 8mmx8mm Holtek HTSSOP-14 package. It is designed for a typical operation temperature range of -40°C to +125°C. Overall, the LP5952TL-1.5EV is an excellent choice for low-cost applications that require high efficiency, low-noise operation, and improved transient response.
