Its 73 dB to 57 dB PSRR at 120 Hz makes it a strong candidate for powering analog front-ends, ADC/DAC reference rails, or sensitive RF stages where supply noise couples into the signal path. The wide -40°C to 125°C operating range covers industrial control cabinets and under-hood automotive modules. Housed in a DDPAK/TO-263-5 (TO-263-6 with 5 leads plus tab), the package is hand-solderable with a basic iron and offers good thermal dissipation through the exposed pad. The tab is the output — the PCB copper area under it sets the effective thermal resistance, so a solid pour on the bottom layer helps keep junction temperature in check at 3 A. Surface-mount only, supplied in tube. The enable pin lets you sequence the rail or shut it down for sleep modes — quiescent current drops to 4 mA typical when active, with a 10 mA supply maximum.","metaTitle":"LP3856ES-2.5/NOPB 3A LDO, 2.5V Fixed, DDPAK-5","metaDescription":"Texas Instruments LP3856ES-2.5/NOPB 3A LDO regulator, fixed 2.5V output, 0.6V dropout, 73-57dB PSRR at 120Hz.

The higher figure applies at light loads; the lower end at full 3 A output. This range is typical for a 3 A LDO — expect better rejection at lower frequencies and some roll-off above 1 kHz."},{"question":"What package does LP3856ES-2.5/NOPB come in?","answer":"It ships in a DDPAK/TO-263-5 (5 leads plus tab), also listed as TO-263-6.
