The 4-X2SON (1x1 mm) package with exposed pad suits space-constrained designs where a clean analog or digital supply is needed close to the load. ## PSRR across the switching band PSRR is specified at 70 dB at 100 Hz, rolling off to 55 dB at 1 MHz. This means the regulator attenuates upstream switching noise from a 1 MHz DC-DC converter by about 55 dB — enough to keep ripple below 1 mV for most sensor and RF front-end rails, provided the input decoupling is adequate. ## Protection and operating range On-chip protection includes over-current, over-temperature, reverse polarity, short-circuit, and under-voltage lockout (UVLO). The enable pin allows external on/off control without a separate power switch. Output configuration is positive, fixed at 1.8V.","metaTitle":"TLV71318PDQNT LDO Regulator, 1.8V Fixed, 150mA, 4-X2SON","metaDescription":"Texas Instruments TLV71318PDQNT linear regulator: 1.8V fixed output, 150mA, PSRR 70-55dB.
