MIC5381-MGYFT-TR Microchip

MIC5380/1 High Performance Dual 150 mA LDOs Features General Description 6-Lead 1 mm x 1 mm FTQFN Package The MIC5380 and MIC5381 are advanced dual LDOs that are ideal for powering space-constrained portable 2.5V to 5.5V Input Voltage Range devices. The MIC5380/1 provide two independently 150 mA Output Current per LDO controlled, high performance 150mA LDOs in an High Output Accuracy 1% Typical ultra-small 1 mm x 1 mm FTQFN package. Low Quiescent Current of 32 A per LDO Ideal for battery powered applications, the MIC5380/1 Stable with 0402 1 F Ceramic Output Capacitors offer 1% typical accuracy, low dropout voltage Low Dropout Voltage 155 mV at 150 mA (155mV at 150mA), and low ground current. The Output Discharge Circuit on MIC5381 MIC5380/1 can also be put into a zero-off-mode current state, drawing virtually no current when disabled. Independent Enable Pins Thermal Shutdown Protection The MIC5380/1 offer fast transient response and high PSRR while consuming minimal operating current. Current Limit Protection When the MIC5381 is disabled, an internal resistive load is automatically applied to the output to discharge Applications the output capacitor. Bluetooth Headsets The MIC5380/1 are available with fixed output voltages Mobile Phones in a lead-free (RoHS compliant) 6-lead 1 mm x 1 mm GPS, PMP, PDAs, DSCs FTQFN package.
