MIC5307

300mA Micropower µCap

Baseband LDO

General Description

Features

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.

• Input voltage range: 2.4V to 5.5V

• Ultra-low IQ: Only 20µA operating current

• Stable with ceramic output capacitor

• Low dropout voltage of 120mV @ 300mA

• High output accuracy

– ±1.0% initial accuracy

– ±2.0% over temperature

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.

• Thermal Shutdown Protection

• Current Limit Protection

The MIC5307 is a µCap design, operating with very small

ceramic output capacitors for stability, reducing required

board space and component cost.

Applications

• Digital Logic Power Supply

• Stand-by power supply

• Cellular phones

The MIC5307 is available in fixed output voltages in the

Thin SOT23-5 package.

• PDAs

• Portable electronics

• Notebook PCs
