Surface-mount assembly with a 0.65 mm pitch — standard reflow profile for lead-free solder works. The small 2x2 mm footprint fits dense mixed-signal boards where a 1.8 V analog rail sits next to a 3.3 V digital core. ## PSRR profile and noise-sensitive rail duty PSRR is specified at 80 dB at 10 Hz, rolling off to 52 dB at 1 kHz. That 80 dB at low frequencies means the regulator attenuates 100 mVpp of 50/60 Hz ripple from a switching pre-regulator down to roughly 10 µVpp at the output — relevant for powering the analog supply pins of a precision ADC or a sensor front-end where the reference noise floor is in the microvolt range. The 52 dB figure at 1 kHz still provides about 400:1 rejection of switching noise from a 1 MHz buck converter's fundamental and its harmonics. For a 16-bit SAR ADC sampling at 10 kSPS, that PSRR keeps the LDO's own noise from dominating the converter's SNR budget. ## Quiescent current and always-on battery life Quiescent current is 2.55 µA typical. In a battery-powered sensor node that spends 99 % of its time in a low-power sleep state, the LDO's own draw is the dominant term in the sleep-mode power budget — 2.55 µA from a 250 mAh coin cell gives a theoretical shelf life of over 11 years before the regulator alone drains the battery. The enable pin (Control Features) lets a host MCU gate the LDO output entirely, cutting the quiescent current to near zero during deep-sleep intervals — useful when multiple voltage domains are sequenced on wake. ## Protection set and input voltage envelope Protection features include over-current, over-temperature, reverse polarity, and under-voltage lockout (UVLO). The reverse-polarity protection means the regulator survives a miswired battery connection — the internal pass FET blocks reverse current without an external Schottky diode. The UVLO threshold typically engages around 2.0 V rising, ensuring the output stays off until the input rail is stable. Product status is Active — no end-of-life notice, no last-time-buy window. Texas Instruments lists the TPS70618DRVT as ROHS3 compliant, covering the EU RoHS exemption list through 2024.","metaTitle":"TI TPS70618DRVT LDO Regulator, 1.8V Fixed, 150mA, 6-WSON","metaDescription":"Texas Instruments TPS70618DRVT linear regulator: 1.8V fixed output, 150mA, PSRR 80dB~52dB (10Hz~1kHz), 2.55µA Iq, -40~125°C.
