The 340mV typical dropout at full load (0.66V max) means the input rail needs at least 3.64V to hold regulation — a 5V bus gives you over a volt of headroom before the output starts to sag. PSRR is 63dB at 120Hz, which is the rectified line-frequency ripple band. For a post-switcher rail feeding sensitive analog or RF stages, this attenuation knocks down 120Hz hum by a factor of roughly 1400 — enough to keep ripple off a VCO supply or a precision ADC reference input. ## Thermal and protection envelope for a 3A LDO The 16-TSSOP exposed-pad package (4.40mm width) is the thermal interface. Built-in protection covers over-current, over-temperature, and reverse polarity — the reverse-polarity clamp means a backwards battery connection won't instantly kill the regulator, though the input supply should still be fused for the fault current. Quiescent current is 1.5 mA typical — not an ultra-low-Iq part for always-on battery nodes, but acceptable for a 3A LDO where the load current dominates the efficiency calculation. The enable pin lets a supervisor or GPIO shut down the rail, dropping Iq to near zero. Lifecycle status is Active — no NRND flag, no last-time-buy window. ROHS3 compliant.","metaTitle":"LT1764AEFE-3.3#PBF LDO Regulator, 3.3V Fixed, 3A, 16-TSSOP","metaDescription":"LT1764AEFE-3.3#PBF 3A LDO, fixed 3.3V output, 63dB PSRR at 120Hz, -40°C to 125°C, active production, ROHS3.
