The enable pin lets the downstream system shut the regulator off when the load is idle, pulling the quiescent current to near-zero. ## 4.5 V fixed output — dropout and PSRR This is a fixed 4.5 V positive-output LDO rated for 200 mA continuous. The maximum dropout is 0.2 V at 150 mA load — meaning the input rail needs to stay above 4.7 V to keep the output in regulation under that load. At lighter loads the dropout is lower, but the headroom budget should be sized for the worst-case 0.2 V figure. PSRR is 73 dB at 1 kHz, which attenuates 1 kHz ripple on the input by a factor of roughly 4500 — useful when the input comes from a switching pre-regulator that switches in the audible range. ## Quiescent current and protection Quiescent current is 60 µA typical — low enough for battery-powered always-on systems but not the lowest in class; the 200 mA output stage draws this overhead continuously. Over-current protection is built in, so a short on the output rail folds back the current without damaging the regulator. ## Temp grade and supply range A 5.0 V ±5% supply is a safer match.","metaTitle":"Toshiba TCR2EF45,LM(CT LDO 4.5V 200mA SMV","metaDescription":"Toshiba TCR2EF45,LM(CT fixed-output LDO, 4.5V at 200mA, PSRR 73dB (1kHz), dropout 0.2V at 150mA, SOT-753, active production, RoHS3.
