Microchip Technology MIC5306-3.0YD5-TR

Description
The MIC5306 is a micropower, μCap low dropout regulator designed for optimal performance in a small space. It can source 150mA of output current and only draws 16μA of operating current. This high-performance LDO offers fast transient response and good PSRR while consuming minimal current.
Ideal for battery-operated applications, the MIC5306 offers 1% accuracy and an extremely low dropout voltage (45mV @ 100mA). Equipped with a TTL logic-compatible enable pin, it 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. It is available in fixed output voltages in Thin SOT23-5 packaging.
