SC4210A  
8-Pin N-FET Linear  
Regulator Controller  
POWER MANAGEMENT  
Features  
Description  
The SC4210A linear regulator controller includes all the  
features required for an extremely low dropout linear  
regulator that uses an external N-channel MOSFET as  
the pass transistor. The device can operate from input  
voltages as low as 1.75V and can provide high current  
levels, thus providing an efficient linear solution for cus-  
tom processor voltages, bus termination voltages, and  
other logic level voltages down to 0.5V. The onboard  
charge pump creates a gate drive voltage capable of driv-  
ing an external N-MOSFET which is optimal for low drop-  
out voltage and high efficiency. The wide versatility of  
this IC allows the user to optimize the setting of both  
current limit and output voltage for applications beyond  
or between standard 3-terminal linear regulator ranges.  
‹ On-board charge pump to drive external N-MOSFET  
‹ Input voltage as low as 1.75V to 5.5V  
‹ Duty ratio mode over-current protection  
‹ Extremely low dropout voltage  
‹ Low external parts count  
‹ Output voltages as low as 0.5V  
‹ MSOP-8 package  
Applications  
‹ Telecom and networking cards  
‹ Industrial applications  
‹ Wireless infrastructure  
‹ Set-top boxes  
‹ Post regulated power supplies  
The 8-pin controller IC features a duty ratio current limit-  
ing technique that provides peak transient loading capa-  
bility while limiting the average power dissipation of the  
pass transistor during fault conditions.  
The SC4210A is available in an MSOP-8 surface mount  
package.
