The Texas Instruments LP5996SD-1833/NOPB is a dual-output linear regulator delivering fixed 1.8V and 3.3V rails. It supports 150mA and 300mA loads respectively, with a low quiescent current of 110µA. The 3.3V channel features a dropout of 0.55V at full load. High PSRR (up to 70dB) ensures clean power for mixed-signal applications. The compact 10-SON (3x3) package makes it suitable for space-constrained portable electronics.
- Mixed-Voltage Support: Provides 1.8V and 3.3V rails, ideal for modern MCUs and peripherals.
- Low Power Standby: 110µA quiescent current minimizes battery drain in sleep modes.
- High PSRR: Up to 70dB rejection keeps digital noise from affecting sensitive circuits.
- Space-Saving Design: 3x3mm SON package fits tight PCB layouts.
