LP5952LC-1.5EV is a low-dropout (LDO) linear voltage regulator integrated circuit from the Voltage Regulators (LDO) family. Designed for a wide range of applications, it provides stable regulation at an output voltage of 1.5V. The output current of this device reaches 150mA, allowing for increased flexibility. With its low-dropout feature, the device can operate at input and output voltages within a small range, making it well suited for applications where input or output voltage drops are expected. Furthermore, the use of advanced process technologies allows for smaller package size and lower power consumption compared to other LDO voltage regulators.

The LP5952LC-1.5EV evaluation board is a reference platform engineered to simplify the evaluation of the LP5952LC-1.5EV linear voltage regulator. It includes onboard devices such as a 4-pin screw/spring terminal block, a test terminal, and a three-position selection switch. This selection switch allows the user to select between an adjustable output voltage or a fixed 1.5V output voltage. The board also features an adjustable current limitation circuit for safety purposes. The onboard circuit allows the user to limit the current sourced by the device when an over-current/short-circuit condition is present.

The LP5952LC-1.5EV board comes in two different versions, one with 0.8ohm and the other with 1.5ohmsPower resistors. The use of 0.8ohm resistors adds a feature allowing the user to generate current monitoring signals when the device is under heavy load. The generated signal can be used as an immediate indication that output current has exceeded its set limit.

The board also features an active input under-voltage lock out circuit (UVLO) as well as a typical ceramic capacitor bypass of the power resistor and test point. This feature prevents the device from operating if the input voltage falls below the specified UVLO threshold. The bypass capacitor and power resistor also ensure improved circuit stability and improved short-term overload performance.

The LP5952LC-1.5EV has its output voltage adjustment point located on the board and uses small surface-mount resistors, making it easy to adjust and facilitate design tuning. Furthermore, the device’s output voltage can be adjusted via a potentiometer or through a digital signal interface. Its low-dropout features allow the device to achieve a low voltage drop while source and sink current up to 150mA and reduce power loss in the system. It is also equipped with hot plug-in/hot plug-out protection, making it ideal for sensitive electronics which may be powered on or off frequently.

The LP5952LC-1.5EV features a wide input voltage range, from 0V up to 22V. This gives it the ability to provide stable regulation under wide line, load and temperature conditions. It also features a low quiescent current of just 4.2mA, reducing power consumption in applications which require both analogue and digital logic. Furthermore, the device’s thermal protection feature allows it to protect itself from over temperature conditions.

To ensure the highest level of safety and reliability, the LP5952LC-1.5EV has been designed in accordance with many industry standards such as IEC60601-1 and IEC60601-2-51. Additionally, the device has been tested for ESD (electro-static discharge) resistance. Furthermore, it has been tested to meet specific requirements for stability in noise, transient, temperature, and current-limit conditions.

In summary, the LP5952LC-1.5EV is a low dropout linear voltage regulator which is designed for a range of applications requiring a fixed 1.5V output voltage. This device features a wide input voltage range, low quiescent current, hot plug-in/hot plug-out protection, and adjustable current limitation functions for improved safety and reliability. Additionally, it has been designed to pass many industry standard tests such as Electro Magnetic Compatibility (EMC) and Electro Static Discharge (ESD) tests. With its small size and low power consumption, the LP5952LC-1.5EV is an ideal choice for a wide range of applications.
