3.1V fixed LDO for tight rails
Key protection features — over-current, over-temperature, reverse polarity, and under-voltage lockout — mean this part handles startup into a pre-biased output or a brief input dip without latching up. 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.
