Power supply rejection is 63 dB at 120 Hz, which is the post-rectifier ripple frequency for a full-wave bridge on a 60 Hz line. This level of rejection attenuates 1 V pk-pk ripple to under 0.7 mV at the output — relevant when the LDO follows a bulk capacitor rather than a switching preregulator. ## Industrial temperature range and protection set The TO-220-5 package with its exposed tab can dissipate several watts when properly heatsunk — the limiting factor is the junction-to-ambient thermal resistance, not the silicon. Built-in protection includes over-current limiting, thermal shutdown, and reverse polarity protection on the input. The reverse polarity feature blocks negative input voltages from reaching the load — a useful safeguard in bench supplies or battery-powered equipment where input polarity can be miswired. ROHS3 compliant per the manufacturer's declaration, covering the EU RoHS exemption list through 2024. The surface-mount sibling LT1963AES8#PBF shares the same 1.5 A output, dropout, PSRR, and protection set in an SOIC-8 package. The TO-220-5 through-hole version is the better choice when board-level heatsinking is needed or when the assembly line prefers through-hole for manual rework.","metaTitle":"LT1963AET#PBF LDO Regulator, 1.5A Adjustable, TO-220-5","metaDescription":"LT1963AET#PBF adjustable LDO regulator, 1.5A output, 340mV dropout, 63dB PSRR at 120Hz.
