MIC5318  
High Performance 300mA  
µCap ULDO™  
General Description  
Features  
The MIC5318 is a high performance, single output  
ultra low drop-out (ULDO™) regulator, offering low  
total output noise in an ultra-small Thin MLF®  
package. The MIC5318 is capable of sourcing 300mA  
output current and offers high PSRR and low output  
noise, making it an ideal solution for RF applications.  
Ultra low dropout voltage 110mV @ 300mA  
Input voltage range: 2.3V to 6.0V  
300mA guaranteed output current  
Stable with ceramic output capacitors  
Ultra low output noise – 30µVrms  
Low quiescent current – 85µA total  
High PSRR > 70dB@1kHz  
Ideal for battery operated applications, the MIC5318  
offers 2% initial accuracy, extremely low dropout  
voltage (110mV @ 300mA), and low ground current  
(typically 85µA total). The MIC5318 can also be put  
into a zero-off-mode current state, drawing no current  
when disabled.  
Less than 35µs turn-on time  
High output accuracy  
± 2% initial accuracy  
± 3% over temperature  
The MIC5318 is available in the 1.6mm x 1.6mm Thin  
MLF® package, occupying only 2.56mm2 of PCB area,  
fully a 36% reduction in board area when compared to  
SC-70 and 2mm x 2mm MLF® packages.  
Thermal shutdown and current limit protection  
Tiny 6-pin 1.6mm x 1.6mm Thin MLF® package  
Thin SOT23-5 package  
The MIC5318 has an operating junction temperature  
range of –40°C to +125°C and is available in fixed and  
adjustable output voltages in lead-free (RoHS  
compliant) Thin MLF® and Thin SOT23-5 packages.  
Applications  
Mobile phones  
PDAs
