That 2A figure is the headline — it tells you the thermal design is the constraint, not the current capability. In a 20-HTSSOP package with an exposed thermal pad, the junction-to-ambient resistance is low enough to handle 2A from a 3.3V rail down to 1.8V (3W dissipation) if the board copper is there to sink it. PSRR is 60dB at 100Hz — that's the noise rejection at line frequency and its harmonics. For an analog supply rail feeding a precision ADC or op-amp chain, 60dB at 100Hz means the 120Hz ripple from a rectifier is attenuated by a factor of 1000. Above 100kHz the PSRR rolls off, so keep the input filter cap close to the VIN pin. ## Industrial temperature range and protection set The protection features listed — over-current, over-temperature, and reverse polarity — cover the common failure modes on a board: a shorted load trips the current limit, a stalled fan or high ambient triggers thermal shutdown, and a swapped input doesn't blow the regulator. The reverse polarity protection is a diode across the input, so the drop is about 0.7V; plan for that in the minimum input margin. ## Control features and package integration The Enable, Power Good, and Reset Output control features give sequencing flexibility: Power Good asserts when the output is within regulation, Reset Output provides a delayed reset signal for the downstream load. The 20-HTSSOP package has a 0.65mm pitch — standard reflow profile, no special handling beyond the usual moisture sensitivity level for that package family.","metaTitle":"TPS75218QPWP Texas Instruments LDO, 2A, 1.8V Fixed","metaDescription":"Texas Instruments TPS75218QPWP LDO regulator, 2A output, fixed 1.8V, 60dB PSRR at 100Hz, -40 to 125°C, 20-HTSSOP.
