Surface-mount only. The 2x2 mm footprint with a single exposed pad is reworkable with hot air if the board has adequate thermal relief vias under the pad — but the pad draws heat fast, so preheat the board to 100°C before lifting the part to avoid lifting the pad. ## Dropout voltage and headroom — 0.14V at full load Maximum dropout voltage is 0.14V at 500 mA output. With a 3.3V max input, there is plenty of headroom — but if the input is a 1.5V rail, the margin is tight and a lower-dropout part may be needed. The fixed 1.2V output is set internally — no external resistor divider needed. The enable pin lets the system shut down the regulator when the load is idle, cutting the 2.6 µA quiescent current to near zero. ## PSRR across frequency — noise rejection for sensitive loads PSRR is 64 dB at 1 kHz, dropping to 35 dB at 1.5 MHz. This is a typical roll-off for a low-Iq LDO — the control loop gain falls above the crossover frequency. For a 2.2 MHz switching regulator feeding this LDO, the noise at the switching frequency will see only 35 dB of rejection, so a post-filter LC stage ahead of the LDO input may be needed if the load is noise-sensitive (ADC reference, RF VCO). The 11 µA maximum supply current (including the pass element) means the LDO's own noise contribution is low — the dominant noise source in the output will be the input ripple that leaks through at high frequencies. ## Protection features — OCP, OTP, UVLO Built-in over-current protection limits the output current during a fault; over-temperature protection shuts the regulator down if the junction exceeds the thermal limit; under-voltage lockout prevents the output from turning on until the input rail is above the UVLO threshold. These three protections let the part survive a shorted load or a stalled fan without external foldback circuitry.","metaTitle":"TPS7A1112PDRVT 500mA LDO, 1.2V Fixed, 6-WSON","metaDescription":"TI TPS7A1112PDRVT: 500mA LDO, fixed 1.2V output, 2.6µA Iq, PSRR 64dB at 1kHz.
