MIC5365/6 
High-Performance Single 150mA LDO 
 
 
 
 
General Description Features 
The MIC5365/6 is an advanced general purpose linear 
 Tiny 1mm  1mm thin MLF, SC-70-5,  
regulator offering high power supply rejection (PSRR) in 
and thin SOT23-5 packages  
an ultra-small 1mm  1mm package. The MIC5366 
 Input voltage range:  2.5V to 5.5V 
includes an auto-discharge feature that is activated when 
 150mA guaranteed output current 
the enable pin is low. The MIC5365/6 is capable of 
 Stable with 1F ceramic output capacitors 
sourcing 150mA output current and offers high PSRR 
making it an ideal solution for any portable electronic  Low dropout voltage  155mV @ 150mA 
application. 
 Excellent load/line transient response 
Ideal for battery-powered applications, the MIC5365/6 
 Low quiescent current  29A 
offers 2% initial accuracy, low dropout voltage (155mV @ 
 High PSRR  70dB 
150mA), and low ground current (typically 29A). The 
 Output discharge circuit  MIC5366 
MIC5365/6 can also be put into a zero-off-mode current 
 High output accuracy 
state, drawing virtually no current when disabled.  
 2% initial accuracy 
The MIC5365/6 is available in several advanced packages 
including a lead-free (RoHS-compliant) 1mm  1mm Thin  Thermal-shutdown and current-limit protection
