The 55 µA quiescent current and 370 µA max supply current suit battery-operated or always-on subsystems where every microamp counts. The -40°C to 125°C junction temperature range qualifies it for automotive under-hood, industrial motor-drive, and outdoor telecom enclosures. ## Dropout headroom and PSRR — what they mean for your rail PSRR is specified at 68 dB at 1 kHz for this 300 mA LDO. ## Enable pin and sequencing The enable pin (active-high) lets you gate the output with a logic signal. Pull it low to shut down the regulator into a near-zero quiescent state — useful for power-gating a sensor or radio between measurement cycles. Tie it to the input if you want the output on whenever input power is present. ## Lifecycle and sourcing The TLV70231DBVT carries an active lifecycle status and is ROHS3 compliant.","metaTitle":"TLV70231DBVT LDO Regulator, 3.1V Fixed Output, 300mA","metaDescription":"TI TLV70231DBVT linear regulator: 3.1V fixed output, 300mA, 0.38V dropout max, 68dB PSRR at 1kHz, -40°C to 125°C.
