For a 3.3V or 5V bus, headroom is generous. ## Package and thermal — DDPAK/TO-263-5 The LP3893ES-1.2/NOPB comes in a DDPAK/TO-263-5 surface-mount package (also known as TO-263-6 with one pin omitted — 5 leads plus the tab). The tab is the output and the main thermal path. For 3A at low dropout, the power dissipation can hit several watts; a proper PCB copper area under the tab is mandatory. The -40°C to 125°C operating range covers industrial and automotive under-hood environments, but the junction temperature at full load depends on your board's thermal resistance. ## Protection features — built-in safety net Over-current, over-temperature, short-circuit, and under-voltage lockout (UVLO) are all on-chip. The UVLO prevents the output from turning on until the input is high enough to regulate cleanly. Over-temperature shutdown protects the die if the heatsinking is inadequate — useful in a retrofit where the board layout is fixed. ## Sourcing and lifecycle — active, no LTB risk Texas Instruments lists the LP3893ES-1.2/NOPB as Active. No last-time-buy notice, no NRND flag. ROHS3 compliant. For current pricing and availability, submit an RFQ — we source and quote to order against your BOM line.","metaTitle":"LP3893ES-1.2/NOPB LDO Regulator, 1.2V Fixed Output, 3A","metaDescription":"Texas Instruments LP3893ES-1.2/NOPB is a 1.2V fixed-output LDO rated for 3A with 80dB PSRR at 120Hz.
