Linear & Switching Voltage Regulators

LP5900SDX-1.8/NOPB Description

The LP5900SDX-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. It operates with an input voltage range up to 5.5V, making it suitable for a variety of low-power applications. The device features an ultra-low quiescent current of 50 µA and a low dropout voltage of 150mV at full load, ensuring efficient power management in battery-operated systems. Packaged in a compact 6-pin WSON (DSBGA) form factor, it is optimized for space-constrained designs while offering excellent thermal performance.

LP5900SDX-1.8/NOPB Features

• High PSRR (85dB at 100Hz): Ensures clean output voltage by effectively rejecting input noise, ideal for noise-sensitive analog and RF circuits.
• Low Quiescent Current (50 µA): Extends battery life in portable devices such as wearables and IoT sensors.
• Enable Pin Control: Allows for power sequencing and standby mode, reducing power consumption when inactive.
• Robust Protection: Includes over-temperature and short-circuit protection for enhanced reliability.
