PSRR is 62 dB at 120 Hz — that is the ripple rejection at the full-wave-rectifier fundamental frequency. A 1 Vpp ripple on the input gets knocked down to roughly 0.8 mVpp on the output, which keeps the 1.8 V rail clean for analog or logic loads that are sensitive to line-frequency hum. Built-in protection covers over-current, over-temperature, and over-voltage — the regulator shuts down or clamps before the load or the pass transistor sees damage. The operating temperature range is 0 °C to 125 °C, so it is rated for indoor equipment and moderate ambient environments, not extended cold or under-hood automotive.","metaTitle":"TLV2217-18KCSE3 Texas Instruments LDO, 1.8V 500mA TO-220-3","metaDescription":"Texas Instruments TLV2217-18KCSE3 fixed-output LDO regulator, 1.8V at 500mA, TO-220-3 package. 62dB PSRR at 120Hz.
