The LP3985ITLX-5.0/NOPB is a high-performance, low dropout (LDO) linear voltage regulator from Texas Instruments, designed to provide a fixed output of 5.0V with a maximum current of 150mA. This component is ideal for battery-powered applications due to its low quiescent current and excellent power supply rejection ratio (PSRR).

Key Features

• Output Voltage: Fixed 5.0V with excellent load and line regulation.
• Output Current: Capable of delivering up to 150mA of continuous current.
• Low Dropout Voltage: Typically 280mV at 150mA load, enabling efficient operation even with very low input-to-output voltage differentials.
• High PSRR: Provides superior power supply noise rejection, making it suitable for RF and other noise-sensitive applications.
• Low Quiescent Current: Ideal for battery-powered devices, with a typical quiescent current of 30µA and 1µA in shutdown mode.
• Stable with Low-ESR Ceramic Capacitors: Stability with output capacitors as low as 1µF for space-saving designs.
• Thermal Shutdown and Short-Circuit Protection: Enhances system reliability through built-in safety features.
• Noise Reduction: An optional bypass pin allows for further reduction of output noise.
• Package: Available in a compact 5-pin SOT-23 package, suitable for space-constrained applications.

Applications

The LP3985ITLX-5.0/NOPB is versatile and can be used in a wide range of applications, including:

• Mobile Phones
