It comes in a SOT-223-6 surface-mount package, rated for -40°C to 125°C operation — suited for industrial sensor rails, automotive always-on supplies, or post-switcher clean-up stages where the load pulls an amp. PSRR is 60 dB at 1 kHz, which knocks down switching ripple from a front-end DC-DC converter. For noise-sensitive loads like an ADC reference or analog front-end, that's a clean enough rail without a second filter stage. ## Protection set — built-in, no extra parts The TPS72516DCQR integrates over-current, over-temperature, reverse polarity, and under-voltage lockout (UVLO). That covers the common fault modes on a 6V max input bus: a shorted load, a hot ambient, a reversed battery connection, or a sagging input. No external supervisor or protection diode needed for most designs. Control features include an enable pin and a reset output — useful for sequencing a downstream load or holding a microcontroller in reset until the rail is stable. ## Lifecycle and sourcing For a BOM line that needs a fixed 1.6V rail at 1A, this part is a current-design fit with no LTB clock ticking.","metaTitle":"TPS72516DCQR LDO Regulator, 1.6V Fixed, 1A, SOT-223-6","metaDescription":"TI TPS72516DCQR linear regulator: 1.6V fixed output, 1A, 60dB PSRR at 1kHz, low dropout 0.32V max, SOT-223-6.
