MIC5309 Low V /V 300mA High PSRR IN OUT ULDO? with Ultra-Low IQ General Description Features The MIC5309 is a high performance, ?Cap low dropout ? Input voltage range: 1.7V to 5.5V regulator, offering ultra-low operating current while ? Guaranteed 300mA over temperature maintaining very fast transient response. The MIC5309 ? Ultra Low dropout voltage of 100mV typical 300mA can source up to 300mA of output current and can ? High PSRR, up to 90dB @ 1kHz regulate down from a low input supply voltage to increase system efficiency. ? Output Voltage range: 0.8V to 2.0V Ideal for battery operated applications; the MIC5309 offers ? Very low ground current ? 23?A under full load extremely low dropout voltage 100mV typically @ 300mA ? Bias supply voltage range: 2.5V to 5.5V load, and low ground current at all load conditions ? Stable with 1?F ceramic output capacitor (typically 23?A). The MIC5309 can also be put into a zero- ? 300mA maximum output current at 1.7V input voltage off-mode current state, drawing virtually no current when ? Very fast transient response ? ideal for digital loads disabled. ? Thermal shutdown and current limit protection The MIC5309 is available in fixed output voltages in the ? ? tiny 6-pin 1.6mm x 1.6mm thin MLF leadless package as ? Tiny 6-pin 1.6mm x 1.6mm Thin MLF package well as the 6-pin TSOT-23 for cost sensitive applications. ?

Input voltage range: 1.7V to 5.5V regulator, offering ultra-low operating current while ? Guaranteed 300mA over temperature maintaining very fast transient response. The MIC5309 ? Ultra Low dropout voltage of 100mV typical 300mA can source up to 300mA of output current and can ? High PSRR, up to 90dB @ 1kHz regulate down from a low input supply voltage to increase system efficiency. ? Output Voltage range: 0.8V to 2.0V Ideal for battery operated applications; the MIC5309 offers ? Very low ground current ? 23?A under full load extremely low dropout voltage 100mV typically @ 300mA ? Bias supply voltage range: 2.5V to 5.5V load, and low ground current at all load conditions ? Stable with 1?F ceramic output capacitor (typically 23?A). The MIC5309 can also be put into a zero- ? 300mA maximum output current at 1.7V input voltage off-mode current state, drawing virtually no current when ? Very fast transient response ? ideal for digital loads disabled. ? Thermal shutdown and current limit protection The MIC5309 is available in fixed output voltages in the ? ? tiny 6-pin 1.6mm x 1.6mm thin MLF leadless package as ? Tiny 6-pin 1.6mm x 1.6mm Thin MLF package well as the 6-pin TSOT-23 for cost sensitive applications. ?
