TECHNICAL NOTE
High-performance Regulator IC Series for PCs
100mA Linear Regulators
for Note PC
BD35602F/HFN/HFV, BD35603F/HFN/HFV, BD35605F/HFN/HFV
●Description
BD3560□ series is a LDO regulator with output current 100mA. The output accuracy is±1% of output voltage. BD3560
□
series have some kinds of output voltage line-up and package line-up. Thus, it is used for the wide applications of
digital appliances. Over current protection (for protecting the IC destruction by output short circuit), shutdown ON/OFF
switch (for setting the circuit current 0μA at shutdown mode), and thermal shutdown circuit (for protecting ICs from heat
destruction by over load condition) are all built in.
●Features
1) Output current 100mA
2) Output voltage accuracy :
±1%
3) Built-in Over Current Protection circuit (OCP)
4) Built-in Thermal Shut Down circuit (TSD)
5) With shut down switch
6) Rich package line-up : HVSOF6, HSON8, SOP8
