Linear & Switching Voltage Regulators

LP5900TL-1.8/NOPB Description

The LP5900TL-1.8/NOPB is a high-performance, low-dropout (LDO) linear voltage regulator from Texas Instruments, designed to deliver a fixed 1.8V output with a maximum current of 150mA. This regulator is optimized for applications requiring ultra-low noise, high power supply rejection ratio (PSRR), and minimal quiescent current. It operates over an input voltage range of 1.9V to 5.5V, making it suitable for battery-powered and noise-sensitive systems. The device is housed in a compact 4DSBGA package, ideal for space-constrained designs, and is available in Tape & Reel (TR) packaging for automated assembly.

LP5900TL-1.8/NOPB Features

• Ultra-Low Dropout Voltage: 0.15V (max) at 150mA, ensuring efficient operation even with low input voltages.
• Low Quiescent Current: 50 µA (typ) minimizes power consumption in standby or battery-operated applications.
• High PSRR: 85dB at 100Hz, reducing noise interference in sensitive analog and RF circuits.
• Robust Protection: Includes over-temperature and short-circuit protection for enhanced reliability.
• Enable Control: Features an enable pin for power management, allowing shutdown mode to further reduce current draw.
• Wide Input Range: Supports 1.9V to 5.5V, compatible with Li-ion batteries, 3.3V, and 5V systems.
• Compact Form Factor: 4DSBGA package (1.0mm x 1.0mm) saves board space in portable and IoT devices.
• Compliance: ROHS3 and REACH compliant, with MSL1 (Unlimited) moisture sensitivity for extended shelf life.

LP5900TL-1.8/NOPB Applications

• Portable Electronics: Ideal for smartphones, tablets, and wearables due to its low Iq and small footprint.
• RF and Analog Circuits: High PSRR makes it suitable for powering noise-sensitive components like ADCs, DACs, and PLLs.
• Battery-Powered Systems: Efficient dropout performance extends battery life in medical devices, sensors, and IoT nodes.
• Industrial and Automotive: Reliable operation under varying temperatures and voltages, suitable for control modules and infotainment systems.
• Embedded Systems: Provides stable voltage to microcontrollers, FPGAs, and memory in space-constrained designs.
