MIC2215-PPPYML-TR

MIC2215 High PSRR, Low Noise Cap Triple LDO Features General Description Input Voltage Range: +2.25V to +5.5V The MIC2215 is a high performance, triple LDO voltage regulator, with each regulator capable of providing 7 0 dB PSRR 250 mA continuous output current. Stable with Ceramic Output Capacitor Ideal for battery-operated applications, the MIC2215 High Output Accuracy: offers 1% initial accuracy, extremely low dropout - 1.0% Initial Accuracy voltage (100 mV 150 mA), and low ground current at - 2.0% over Temperature light load (typically 110 A per regulator). Equipped Low Dropout Voltage of 100 mV 150 mA with a noise bypass pin and featuring very high power Low Quiescent Current: 110 A per Regulator supply ripple rejection (PSRR) of up to 80 dB, the MIC2215 provides the lowest noise and highest Fast Turn-On T ime: 30 s efficiency solution for RF applications in portable Zero Off-Mode Current electronics such as cellular phones and wireless LAN Thermal Shutdown Protection applications. Current Limit Protection Equipped with TTL logic-compatible enable pins, each T iny 16-Pin 4 mm x 4 mm QFN Package of the regulators in the MIC2215 can be put into a zero current off mode where the supply current is much less Applications than 1 A when all the regulators are disabled. The MIC2215 is a Cap design, which enables a stable Cellular Phones output with small ceramic output capacitors, reducing PCs and Peripherals both cost and required board space for output Wireless LAN Cards bypassing. PDAs The MIC2215 is available in the miniature 16-pin, GPS 4 mm x 4 mm QFN package. Package Types MIC2215-XXX MIC2215-AAA 16-Lead QFN (ML) (Fixed) 16-Lead QFN (ML) (Adj.)
