Microchip Technology

The MIC5309 is a high performance, µCap low dropout regulator that offers ultra-low operating current while maintaining very fast transient response. The MIC5309 can source up to 300mA of output current and can regulate down from a low input supply voltage to increase system efficiency. Ideal for battery-operated applications; the MIC5309 offers extremely low dropout voltage (100mV typically at 300mA load) and low ground current at all load conditions (typically 23µA). The MIC5309 can also be put into a zero off-mode current state, drawing virtually no current when disabled.

The MIC5310 is a tiny Dual Ultra Low-Dropout (ULDO) linear regulator ideally suited for portable electronics due to its high power supply ripple rejection (PSRR) and ultra low output noise. The MIC5310 is a µCap design which enables operation with very small ceramic output capacitors for stability, thereby reducing required board space and component cost. The combination of extremely low-drop-out voltage, high power supply rejection and exceptional thermal package characteristics makes it ideal for powering RF/noise-sensitive circuitry, cellular phone camera modules, imaging sensors for digital still cameras, PDAs, MP3 players and webcam applications

The MIC5316 is a high performance, dual low input voltage, low dropout regulator with Power on Reset (POR) and voltage select. Major features include two 300mA LDOs, input voltage down to 1.7V, ultra low drop out of 85mV at full load, Power on Reset, and voltage select. Each LDO has its own low voltage input for system flexibility. The low input voltages and low drop out operation provides high efficiency by reducing the input to output voltage step which minimizes the regulator power loss. Voltage select is incorporated into the second output, which reduces the output voltage to further save power while in stand-by mode. An adjustable delay time POR output is provided for the second regulator for design flexibility. Ideal for battery operated applications; the MIC5316 offers 1% accuracy and low ground current to increase light load efficiency. The MIC5316 can also be put into a zero off-mode current state, drawing virtually no current when disabled.
