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.
Additional Features
Input voltage range: 1.7V to 5.5V
Guaranteed 300mA over temperature
Ultra-low dropout voltage: 100mV for typical 300mA load
High PSRR: up to 90dB at 1kHz
Output Voltage range: 0.8V to 2.0V
Very low ground current: 23µA under full load
Bias supply voltage range: 2.5V to 5.5V
Stable with 1µF ceramic output capacitor
300mA maximum output current at 1.7V input voltage
Very fast transient response ideal for digital loads
Thermal shutdown and current limit protection
Cost effective 6-pin TSOT-23 package
