Without that, the 300 mA output derates early in still air. Surface-mount only, tape-and-reel or cut-tape options for prototyping. ## Dropout and quiescent — the battery-life numbers The dropout voltage is 90 mV maximum at 300 mA output — that is a low headroom requirement. If the input rail is a 1.2 V or 1.8 V supply, the 1.1 V output stays in regulation with only 90 mV of margin. The quiescent current is 2.6 µA typical, with a maximum supply current of 9 µA. That Iq is low enough for always-on domains in battery-powered gear — a sensor node that sleeps most of the time won't drain the cell through the regulator's own draw. ## PSRR across frequency — 60 dB at 1 kHz to 35 dB at 1.5 MHz The PSRR is specified as 60 dB at 1 kHz, rolling off to 35 dB at 1.5 MHz. That 35 dB at the high end is still about 56× rejection — enough to keep switching ripple from a preceding DC-DC converter from coupling into the 1.1 V rail. The roll-off matters: if the upstream switcher runs at 2 MHz, the rejection at that frequency is below 35 dB, so a pi filter ahead of the LDO may be needed for noise-sensitive loads like analog front-ends or PLL supplies. ## Protection and control — enable pin, OCP, OTP, UVLO The regulator includes an enable pin for on/off control, plus over-current, over-temperature, and under-voltage lockout protection. The UVLO threshold is set internally — no external resistor divider needed.","metaTitle":"Texas Instruments TPS7A1011PDSER LDO, 1.1V Fixed, 300mA","metaDescription":"TI TPS7A1011PDSER LDO regulator, 1.1V fixed output, 300mA, 90mV dropout at full load, 2.6µA Iq, 6-WSON package, -40~125°C.
