Key Features
- Current-mode PWM step-down regulator with 3 V to 5.5 V input range and adjustable output from 0.6 V to 4.5 V for versatile power supply designs
- High switching frequency PWM control enabling use of small external inductors and capacitors, reducing total solution size and BOM cost
- Compact 10-pin SON package (S-PDSO-N10) for space-constrained portable and battery-powered applications
Applications
The LM2833XSD is well-suited for step-down power conversion in portable consumer electronics, wearables, and battery-powered IoT devices operating from single-cell lithium or USB power rails. Its adjustable output voltage from 0.6 V to 4.5 V makes it versatile for powering processors, FPGAs, and low-voltage peripherals with a single regulator. The current-mode PWM architecture provides fast transient response and excellent line/load regulation for noise-sensitive digital and analog loads.

Frequently Asked Questions
What is the input voltage range of the LM2833XSD?
The LM2833XSD accepts an input voltage from 3 V to 5.5 V with a nominal 5 V operation, making it compatible with USB power supplies, single-cell lithium-ion batteries, and standard 5 V regulated power rails.
What output voltage range can the LM2833XSD produce?
The LM2833XSD can produce an adjustable output voltage from 0.6 V to 4.5 V using external resistors, enabling a single device to power a wide range of digital and analog loads including microprocessors, DSPs, and memory devices.
What control mode does the LM2833XSD use?
The LM2833XSD uses current-mode pulse width modulation (PWM) control, which provides inherent cycle-by-cycle current limiting, fast transient response, and easier compensation compared to voltage-mode converters.
What package does the LM2833XSD use?
The LM2833XSD is housed in a 10-pin SON (Small Outline No-lead) package with JEDEC code S-PDSO-N10, offering a compact, low-profile footprint ideal for high-density PCB layouts in portable and space-constrained applications.
Is the LM2833XSD RoHS compliant?
The LM2833XSD has a Pbfree Code of No in the specification data, indicating it may contain lead. Users designing for RoHS-restricted markets should verify the specific date code and consult the Texas Instruments product page for current compliance status.
