Product Overview: LP2985IM5X-3.0

The LP2985IM5X-3.0 is a high-performance, low-noise, low-dropout voltage regulator from Texas Instruments, designed to deliver a fixed output of 3.0 volts. This regulator is part of the LP2985 series, which is known for its exceptional stability and power supply rejection ratio (PSRR), making it an ideal choice for sensitive applications requiring a consistent voltage supply.

Key Features

• Output Voltage: Precisely regulated 3.0V output, suitable for a wide range of applications.
• High Accuracy: Output voltage accuracy is maintained within ±0.5% over temperature, line, and load variations.
• Low Dropout: The low dropout voltage (typically 280 mV at full load) ensures efficient operation even when the input voltage is close to the output voltage.
• Load Current: Capable of supplying up to 150 mA of load current, making it suitable for powering small to medium-sized devices.
• Low Noise: With an ultra-low noise output, this regulator is perfect for RF and precision analog circuits.
• Stable with Low ESR Capacitors: The device remains stable with ceramic capacitors as low as 1 µF, providing flexibility in design.
• Thermal Shutdown and Current Limit Protection: Built-in safety features protect the device under abnormal conditions.

Applications

The LP2985IM5X-3.0 is suitable for a variety of applications, including but not limited to:

• Battery-powered devices
• Portable and handheld equipment
• Reference voltage sources
• Power supplies for cameras, audio devices, and RF applications

Package and Availability

This voltage regulator is offered in a compact SOT-23-5 package, which is ideal for space-constrained applications.
