MIC5306

MIC5306 150mA Micropower µCap Baseband LDO General Description The MIC5306 is a micropower, µCap low dropout regulator designed for optimal performance in a small space. It is capable of sourcing 150mA of output current and only draws 16µA of operating current. This high performance LDO offers fast transient response and good PSRR while consuming a minimum of current. Ideal for battery operated applications; the MIC5306 offers 1% accuracy, extremely low dropout voltage (45mV @ 100mA). Equipped with a TTL logic compatible enable pin, the MIC5306 can be put into a zero-off-mode current state, drawing no current when disabled. The MIC5306 is a µCap design, operating with very small ceramic output capacitors for stability, reducing required board space and component cost. The MIC5306 is available in fixed output voltages in Thin SOT23-5 packaging. Features Input voltage range: 2.25V to 5.5V Ultra-low IQ: Only 16µA operating current Stable with ceramic output capacitor Low dropout voltage of 45mV @ 100mA High output accuracy - ±1.0% initial accuracy - ±2.0% over temperature Thermal Shutdown Protection Current Limit Protection Applications Digital Logic Power Supply Stand-by power supply Cellular phones PDAs Portable electronics Notebook PCs _________________________________________________________________________________________________________ Typical Application 20 18 16 14 12 10 8 6 4 2 0 VOUT = 2.8V VIN = VOUT + 1V COUT = 1µF TEMPERATURE (°C) Gr...
