MIC5307

www.DataSheet4U.com MIC5307 300mA Micropower µCap Baseband LDO General Description The MIC5307 is a micropower, µCap low dropout regulator designed for optimal performance where smaller packages are required. It is capable of sourcing 300mA of output current while only drawing 20µA 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 MIC5307 offers 1% initial accuracy, extremely low dropout voltage and is equipped with a TTL logic compatible enable pin. The MIC5307 can be put into a zero-off-mode current state, drawing no current when disabled. The MIC5307 is a µCap design, operating with very small ceramic output capacitors for stability, reducing required board space and component cost. The MIC5307 is available in fixed output voltages in the Thin SOT23-5 package. Data sheets and support documentation can be found on Micrel’s web site at www.micrel.com.
