MIC5205  
150mA Low-Noise LDO Regulator  
General Description  
Features  
The MIC5205 is an efficient linear voltage regulator with  
ultra low-noise output, very low dropout voltage (typically  
17mV at light loads and 165mV at 150mA), and very low  
ground current (600A at 100mA output). The MIC5205  
offers better than 1% initial accuracy.  
Ultra-low-noise output  
High output voltage accuracy  
Guaranteed 150mA output  
Low quiescent current  
Low dropout voltage  
Designed especially for hand-held, battery-powered  
devices, the MIC5205 includes a CMOS or TTL compatible  
enable/shutdown control input. When shut down, power  
consumption drops nearly to zero. Regulator ground  
current increases only slightly in dropout, further  
prolonging battery life.  
Extremely tight load and line regulation  
Very low temperature coefficient  
Current and thermal limiting  
Reverse-battery protection  
“Zero” off-mode current  
Key MIC5205 features include a reference bypass pin to  
improve its already excellent low-noise performance,  
reversed-battery protection, current limiting, and  
overtemperature shutdown.  
Logic-controlled electronic enable  
Applications  
The MIC5205 is available in fixed and adjustable output  
voltage versions in a small SOT-23-5 package.  
Cellular telephones  
Laptop, notebook, and palmtop computers  
Battery-powered equipment  
For low-dropout regulators that are stable with ceramic  
output capacitors, see the µCap MIC5245/6/7 family.  
PCMCIA VCC and VPP regulation/switching  
Consumer/personal electronics  
SMPS post-regulator/dc-to-dc modules  
High-efficiency linear power supplies
