High Performance Regulators for PCs  
Nch FET Ultra LDO  
for Desktop PCs  
BD35281HFN  
No.11030EAT38  
Description  
The BD35281HFN ultra low-dropout linear regulator operates from a very low input supply, and offers ideal performance in  
low input voltage to low output voltage applications. It incorporates a built-in N-MOSFET power transistor to minimize the  
input-to-output voltage differential to the ON resistance (RON max=150mΩ) level. By lowering the dropout voltage in this way,  
the regulator realizes high current output (Iomax=1.5A) with reduced conversion loss, and thereby obviates the switching  
regulator and its power transistor, choke coil, and rectifier diode. Thus, the BD35281HFN designed to enable significant  
package profile downsizing and cost reduction. In BD35281HFN, The NRCS (soft start) function enables a controlled output  
voltage ramp-up, which can be programmed to whatever power supply sequence is required.  
Features  
1) Internal high-precision reference voltage circuit (0.65V±1%)  
2) Internal high-precision output voltage circuit  
3) Built-in VCC undervoltage lockout circuit (VCC=3.80V)  
4) NRCS (soft start) function reduces the magnitude of in-rush current  
5) Internal Nch MOSFET driver offers low ON resistance (100mΩ typ)  
6) Built-in short circuit protection (SCP)  
7) Built-in current limit circuit (1.5A min)  
8) Built-in thermal shutdown (TSD) circuit  
9) Small package HSON8 : 2.9mm×3.0mm×0.6mm  
10) Tracking function  
Applications  
Notebook computers, Desktop computers, LCD-TV, DVD, Digital appliances
