MIC2215 Triple High PSRR, Low Noise Cap LDO General Description Features The MIC2215 is a high performance, triple LDO voltage Input voltage range: +2.25V to +5.5V regulator, with each regulator capable of providing 250mA 70dB PSRR continuous output current. Stable with ceramic output capacitor Ideal for battery operated applications, the MIC2215 offers High output accuracy: 1% initial accuracy, extremely low dropout voltage (100mV 1.0% initial accuracy 150mA), and low ground current at light load (typically 2.0% over temperature 110A per regulator). Equipped with a noise bypass pin and featuring very high power supply ripple rejection Low dropout voltage of 100mV 150mA (PSRR) of up to 80dB, the MIC2215 provides the lowest Low quiescent current:110A per regulator noise and highest efficiency solution for RF applications in Fast turn-on time:30s portable electronics such as cellular phones and wireless Zero off-mode current LAN applications. Thermal shutdown protection Equipped with TTL logic-compatible enable pins, each of the regulators in the MIC2215 can be put into a zero Current-limit protection current off mode where the supply current is much less Tiny 16-pin (4mm 4mm) MLF package than 1A when all the regulators are disabled. The MIC2215 is a Cap design, which enables a stable output Applications with small ceramic output capacitors, reducing both cost and required board space for output bypassing. Cellular phones The MIC2215 is available in the miniature 16-pin, PCs and peripherals (4mm4mm) MLF package.
