LP3996SD-3333/NOPB TI LDO Regulator | 10-WSON (3X3) | Dual Output, 3.3V/3.3V

Product Overview

The LP3996SD-3333/NOPB is a dual-output, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver two independent 3.3V outputs with high accuracy and low noise. Housed in a compact 10-WSON (3x3 mm) package, this device is ideal for space-constrained applications requiring multiple voltage rails. Each output can supply up to 150 mA, with a dropout voltage as low as 120 mV at full load. The LP3996SD-3333/NOPB features enable pins for each output, allowing independent power sequencing, and includes overcurrent and thermal shutdown protection. Its low quiescent current (typical 30 µA per channel) makes it suitable for battery-powered devices.
