ON Semiconductor LP2951CD-3.3 Low Dropout Voltage Regulator

The ON Semiconductor LP2951CD-3.3 is a versatile, low power voltage regulator with a fixed output of 3.3 volts, designed to offer a stable and reliable power supply for a wide range of electronic applications. This regulator is particularly well-suited for battery-powered devices, portable electronics, and other systems where power efficiency is crucial.

With its low dropout voltage feature, the LP2951CD-3.3 ensures efficient operation even when the input voltage is very close to the output voltage, minimizing power loss and heat generation. This makes it an excellent choice for applications where the power source has a limited voltage range, such as single lithium-ion battery-powered devices.

Key Features:

• Fixed Output Voltage: Precisely regulated 3.3 V output to power sensitive electronics.
• Low Dropout Voltage: Efficient operation with minimal voltage overhead, making it ideal for low-voltage applications.
• Low Quiescent Current: The device consumes a very low amount of current when in operation, which is essential for battery conservation in portable applications.
• Error Flag Warning: An error flag output warns of a low output voltage, which is often due to falling input voltage or excessive load conditions.
• Current and Thermal Limiting: Built-in features protect the device from over-current and over-temperature conditions, ensuring long-term reliability.
• Shutdown Capability: The regulator can be switched off to minimize power consumption when not in use.

The LP2951CD-3.3 is available in a compact SOIC-8 package, which allows for efficient use of board space in space-constrained applications. It is also characterized for operation over a full −40°C to +125°C temperature range, accommodating a wide variety of operating conditions.

Whether you're designing a new piece of portable electronics, looking to improve the power efficiency of an existing device, or simply need a reliable power management solution, the ON Semiconductor LP2951CD-3.3 low dropout voltage regulator is an excellent choice that combines performance, versatility, and reliability.
