Its headline spec is 98dB of PSRR at 1kHz — that means it attenuates power-supply ripple by nearly four orders of magnitude at that frequency, making it a strong choice for analog or RF front-end rails where upstream switching noise would otherwise couple into the signal path. ## Dropout and quiescent current — the real load-bearing specs Maximum dropout is 0.14V at the full 500mA load. Quiescent current is 36µA typical, which keeps the regulator's own draw low enough for battery-powered designs that spend most of their time in light-load or sleep states. ## Package, thermal pad, and board integration Housed in a 4-XDFN exposed pad package with a 1.2x1.2mm footprint (5-DFNB), this is a surface-mount part requiring the PCB land pattern to include a thermal via array under the exposed pad for heat sinking. ## Active lifecycle and compliance posture It is ROHS3 compliant — no restricted substances above the exemption thresholds. The fixed 1.1V output and 5.5V maximum input define the supply rails it can serve; there is no adjustable version in this series for the same package. ## Protection and control features for system-level robustness Built-in over-current and over-temperature protection means the regulator survives a hard short on the output or an ambient spike without immediate failure — the thermal shutdown cycles the output until the die cools. The enable pin allows the system microcontroller to power down the rail, dropping the quiescent current to near zero in standby.","metaTitle":"Toshiba TCR5BM11A,L3F LDO Regulator, 1.1V Fixed, 500mA","metaDescription":"Toshiba TCR5BM11A,L3F LDO voltage regulator. 1.1V fixed output, 500mA, 98dB PSRR at 1kHz.
