The LP38690SD-ADJ/NOPB from Texas Instruments is a versatile adjustable linear regulator capable of delivering up to 1A. Its output can be set from 1.25V up to 9V using external resistors, providing flexibility for various rail requirements. With a low 55 µA quiescent current and a dropout of 1.6V at full load, it balances efficiency and performance. The compact 6-WSON package is ideal for space-constrained industrial and automotive applications.
- High Current Capacity: Delivers up to 1A, suitable for powering FPGAs, DSPs, and other high-current loads.
- Adjustable Output Flexibility: Output voltage can be set from 1.25V to 9V, accommodating a wide range of design requirements.
- Low Quiescent Current: The 55 µA quiescent current helps reduce standby power consumption in battery-operated equipment.
- Compact WSON Package: The 3x3mm WSON package minimizes PCB footprint, ideal for dense layouts.
High-Current FPGA Core Supplies
The 1A output capability makes it suitable for powering FPGA core logic or DSPs that require up to 1A at adjustable voltages, with the 1.6V dropout allowing operation from a 3.3V rail.
Post-Regulation for Switching Converters
Its 55dB PSRR at 120Hz helps clean ripple from a buck converter, providing a stable, low-noise supply for audio codecs or precision ADCs.
Automotive Infotainment Systems
With adjustable output up to 9V, it can power display panels or sensor bias circuits in car infotainment units, handling the 1A peaks during backlight transitions.
Industrial Actuator Control
For driving valves or motors requiring up to 1A, this LDO provides a clean, adjustable supply, reducing electrical noise that could interfere with nearby control logic.
Battery-Powered Test Equipment
The 55 µA quiescent current and adjustable output allow efficient power management in handheld multimeters or signal generators, extending battery life while maintaining accuracy.
