LP3996QSD-1833/NOPB TI Dual LDO | 10-WSON (3x3) | 1.8V/3.3V Output, 150mA

Product Overview

The LP3996QSD-1833/NOPB is a dual-channel low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver high performance in space-constrained applications. Housed in a compact 10-WSON (3x3 mm) package, this device provides two independent output voltages: 1.8V and 3.3V, each capable of sourcing up to 150mA. With a low dropout voltage of typically 120mV at full load, it ensures efficient operation even when the input voltage is close to the output. The LP3996QSD-1833/NOPB features enable pins for each output, allowing independent power management. Its wide input voltage range of 2.5V to 6.0V makes it suitable for battery-powered and industrial systems. The device includes overcurrent and thermal shutdown protection, enhancing system reliability.
