The 68 dB PSRR at 1 kHz means ripple from a switching pre-regulator is attenuated by a factor of ~2500 at that frequency, keeping the output clean for noise-sensitive loads like analog sensor front-ends or ADC reference rails. ## Dropout and quiescent current Maximum dropout is 0.375 V at the full 300 mA load — the input rail needs to stay above 3.375 V to maintain regulation across temperature and process corners. Quiescent current is 55 µA typical, rising to 370 µA max under supply current; this makes the part suitable for battery-powered equipment where the regulator's own draw must stay below a few hundred microamps. Housed in the SOT-23-5 (SC-74A) package, the TLV70330DBVR is a surface-mount device with a 1.6 mm × 2.9 mm footprint — a common outline for portable and space-constrained boards. ## Protection and control features Built-in over-current protection and a current-limit control feature guard the regulator and downstream circuitry against short-circuit events. The output is fixed at 3 V with positive configuration and a single regulator channel.","metaTitle":"TLV70330DBVR LDO Regulator, 3V Fixed, 300mA, SOT-23-5","metaDescription":"Texas Instruments TLV70330DBVR LDO regulator: 3V fixed output, 300mA, 55µA quiescent current, 68dB PSRR at 1kHz.
