LM26484  
Power Management Unit  
General Description  
The LM26484 is a multi-function, configurable Power Man-  
agement Unit. This device integrates two highly efficient 2.0A  
Step-Down DC/DC converters, one LDO Controller, a POR  
(Power On Reset) circuit, and thermal overload protection  
circuitry. All regulator output voltages are externally ad-  
justable. The LDO controller is a low-voltage NMOS voltage  
regulator. The LM26484 is offered in a 5 x 4 x 0.8 mm LLP-24  
pin package.  
LINEAR REGULATOR (LDO) CONTROLLER  
3.0V–5.5V Input range  
Externally adjustable VOUT  
±1.5% feedback voltage accuracy  
Regulated to Low VIN - Low VOUT LI-LO (Low Input Low  
Output) NFET operation  
Input to the LI-LO configuration, can be post regulated  
when supply is regulated by Buck2  
Up to 1000 mA output current by selection of external FET
