Description

The LP2950ACZ-3.3 is a low-dropout (LDO) voltage regulator designed to provide a stable 3.3V output from a higher input voltage. It is part of the LP2950 series, which is well-regarded for its low quiescent current, high accuracy, and excellent line and load regulation. This particular variant, the LP2950ACZ-3.3, is optimized for applications requiring a fixed 3.3V output.
Key features include a low dropout voltage, typically around 50 mV at a 100 mA load, making it ideal for battery-powered devices. It also offers overcurrent and thermal protection to safeguard against excessive load conditions. The regulator is capable of supplying up to 100 mA of output current. The TO-92 package type is common for this model, ensuring easy handling and integration into a variety of circuit designs.
Its high accuracy, within ±0.5% of the specified output voltage over temperature variations, makes it suitable for sensitive electronic applications, including microcontroller power supplies, embedded systems, and low-power devices.
