MIC5308 Low V /V 150mA High PSRR IN OUT ULDO? with Ultra-Low IQ General Description Features The MIC5308 is a high performance, ?Cap low dropout ? Input voltage range: 1.6V to 5.5V regulator, offering ultra-low operating current while ? Guaranteed 150mA over temperature maintaining very fast transient response. The MIC5308 ? Ultra Low dropout voltage of 45mV at 150mA can source up to 150mA 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 MIC5308 offers ? Very low ground current ? 23?A under full load extremely low dropout voltage 45mV typically @ 150mA, ? Bias supply voltage range: 2.5V to 5.5V and low ground current at all load conditions (typically ? Stable with 1?F ceramic output capacitor 23?A). The MIC5308 can also be put into a zero-off-mode ? 150mA maximum output current at 1.6V input voltage current state, drawing virtually no current when disabled. ? Very fast transient response ? ideal for digital loads The MIC5308 is available in fixed output voltages in the ? ? Thermal shutdown and current limit protection tiny 6-pin 1.6mm x 1.6mm thin MLF leadless package as ? well as the 6-pin TSOT-23 for cost sensitive applications. ?

Input voltage range: 1.6V to 5.5V regulator, offering ultra-low operating current while ? Guaranteed 150mA over temperature maintaining very fast transient response. The MIC5308 ? Ultra Low dropout voltage of 45mV at 150mA can source up to 150mA 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 MIC5308 offers ? Very low ground current ? 23?A under full load extremely low dropout voltage 45mV typically @ 150mA, ? Bias supply voltage range: 2.5V to 5.5V and low ground current at all load conditions (typically ? Stable with 1?F ceramic output capacitor 23?A). The MIC5308 can also be put into a zero-off-mode ? 150mA maximum output current at 1.6V input voltage current state, drawing virtually no current when disabled. ? Very fast transient response ? ideal for digital loads The MIC5308 is available in fixed output voltages in the ? ? Thermal shutdown and current limit protection tiny 6-pin 1.6mm x 1.6mm thin MLF leadless package as ? well as the 6-pin TSOT-23 for cost sensitive applications. ? Tiny 6-pin 1.6mm x 1.6mm Thin MLF package Data sheets and support documentation can be found on ? Cost effective 6-pin TSOT-23 package Micrel?s web site at: www.micrel.com. Applications ?
