The enable pin (Control Features) allows the regulator to be shut down for sequencing or power-save modes. Quiescent current sits at 1.5 mA — not an ultra-low-Iq part, but reasonable for a 1.5 A LDO where the load current dominates the power budget. ## Active lifecycle — no end-of-life concern The LT1963EST-1.8#PBF carries an Active product status and is ROHS3 compliant. There is no last-time-buy or NRND notice on this order code. The SOT-223-3 package is a common footprint, so second-sourcing or alternate pin-compatible parts exist in the LT1963 family if dual-source requirements arise.","metaTitle":"LT1963EST-1.8#PBF LDO Regulator, 1.8V Fixed, 1.5A, SOT-223-3","metaDescription":"LT1963EST-1.8#PBF LDO regulator from Analog Devices: 1.8V fixed output, 1.5A, 63dB PSRR at 120Hz, -40°C to 125°C.

For a 1.8 V fixed output in a different package, the LT1963AES8-1.8#PBF (SOIC-8) is a pin-compatible alternate if the SOT-223-3 footprint is not required.
