The LP3996SD-2533 is a dual-output LDO regulator from National Semiconductor, providing fixed 2.5V and 3.3V rails. It supports 150mA and 300mA respectively, with dropout voltages as low as 0.22V. The 100 µA quiescent current and excellent PSRR (up to 70dB) make it ideal for multi-rail portable electronics in a 10-WSON package.
- Dual Outputs: Two independent regulated rails (2.5V and 3.3V) reduce component count.
- High PSRR: Up to 70dB rejection at 1kHz ensures clean power for mixed-signal circuits.
- Compact Solution: 10-WSON (3x3mm) package integrates two regulators in minimal space.
- Low Quiescent Current: 100 µA total for both channels is efficient for battery operation.
Dual-Voltage MCU Systems
Provides both 2.5V (for I/O) and 3.3V (for core) rails from a single regulator, simplifying power design in mixed-voltage microcontrollers.
Smartphone Peripheral Power
Powers camera sensors (2.5V) and display drivers (3.3V) simultaneously, with 58-45dB PSRR at 1-20kHz filtering switching noise.
Portable GPS Modules
Supplies clean power to RF front-end (3.3V) and baseband processor (2.5V), with 70-60dB PSRR on the second channel for sensitive RF circuits.
Battery Management ICs
Regulates separate rails for fuel gauge (2.5V) and protection circuitry (3.3V) in battery packs.
Multi-Sensor IoT Nodes
