The LP2985IM5-2.0 from Texas Instruments is a highly stable, low-dropout linear voltage regulator designed to deliver a fixed output of 2.0 volts. Offering excellent accuracy, low noise, and a high power supply rejection ratio (PSRR), this regulator is an ideal choice for sensitive RF and other analog circuitry that require a stable power supply.

Key Features:

• Output Voltage: Precisely regulated 2.0V output, with an impressive accuracy of ±0.5% at 25°C and ±1% across the full operating temperature range.
• High Current Capacity: Capable of sourcing up to 150mA of output current, making it suitable for a variety of low-power applications.
• Low Dropout: With a very low dropout voltage, typically only 280mV at full load, it ensures efficient operation even when the input voltage is close to the output voltage.
• Low Noise: Provides a quiet power source with a low output noise of 30µVRMS, which is crucial for RF and precision analog applications.
• Stable with Low-ESR Capacitors: Stable with ceramic capacitors, which have lower equivalent series resistance (ESR) than tantalum or aluminum electrolytic capacitors, offering better performance in terms of ripple rejection and transient response.
• Power Supply Rejection Ratio (PSRR): Excellent PSRR of 62dB at 1kHz, minimizing the effects of fluctuations in the input voltage on the output voltage.
• Thermal Protection: Built-in thermal shutdown protection to prevent damage from overheating.
• Current Limiting: Features current limiting to protect the regulator and the load from short-circuit conditions.
