Its 73 dB PSRR at 1 kHz means ripple on the input rail at that frequency is attenuated by a factor of ~4500 — a 10 mVpp switching ripple on a 5 V bus becomes roughly 2.2 µVpp at the output, which keeps noise off sensitive analog or RF supply rails. The dropout voltage is 0.2 V max at 150 mA load, so a 3.3 V input rail with 300 mV of headroom still holds regulation down to the last 100 mV before dropout. Below that, the output falls out of spec — budget the dropout figure into your rail-stack calculation. ## 60 µA quiescent — the always-on cost Quiescent current is 60 µA typical. In a battery-powered sensor waking once a minute to take a reading, that 60 µA draw on the always-on LDO dominates the sleep budget — a 500 mAh cell loses about 1.4 mAh per day just to the regulator's own consumption. If the load sleeps at 10 µA, the LDO's Iq is six times the load current; a lower-Iq LDO may be worth the swap for multi-year deployments. The enable pin (active-high) lets a microcontroller or power-management IC shut the output completely, cutting Iq to near zero in standby. This is the typical approach for sequenced power-up or for gating a 3 V rail that only needs to be live during active operation. ## Package and temperature grade Housed in a 5-pin SC-74A (SOT-753) package, supplier device package designation SMV. ## Lifecycle and compliance Over-current protection is built in — the output current is limited if the load exceeds the rated 200 mA, preventing damage to the regulator and downstream circuitry during a fault.","metaTitle":"Toshiba TCR2EF30,LM(CT LDO, 3V Fixed, 200mA, SC-74A","metaDescription":"TCR2EF30,LM(CT from Toshiba: 3V fixed-output LDO, 200mA, 73dB PSRR at 1kHz, 0.2V dropout at 150mA, 60µA Iq, -40°C to 85°C, SC-74A.
