TECHNICAL NOTE

High-performance Regulator IC Series for PCs

Ultra Low Dropout

Linear Regulators for PC Chipsets

BD3506F, BD3506EFV

Description

The BD3506F/EFV is an ultra-low dropout linear regulator for chipset that can achieve ultra-low voltage input to ultra-low

voltage output. By using N-MOS FET for built-in power transistor, the regulator can be used at ultra-low I/O voltage

difference up to voltage difference generated by ON resistor (Ron = 120 mΩ/100 mΩ). Because by reducing the I/O

voltage difference, large current (Iomax = 2.5A) output is achieved and conversion loss can be reduced, switching power

supply can be replaced. BD3506F/EFV does not need any choke coil, diode for rectification and power transistor which

are required for switching power supply, total cost of the set can be reduced and compact size can be achieved for the set.

Using external resistors, optional output from 0.65V to 2.5V can be set. In addition, since voltage output start-up time can

be adjusted by using the NRCS terminal, it is possible to meet the power supply sequence of the set.

Features

1) Built-in high-accuracy reference voltage circuit (0.65V±1%)

2) Built-in VCC low input maloperation prevention circuit (Vcc = 4.15V)

3) Reduced rush current by NRCS

4) Built-in ultra-low on-resistor (120/100 mΩ typ) Nch Power MOSFET (BD3506F/BD3506EFV)

5) Built-in current limiting circuit (2.5A min)

6) Built-in thermal shutdown circuit

7) Output variable type (0.65-2.5V)

8) Adoption of SOP8 package (BD3506F): 5.0 x 6.2 x 1.5 (mm)

9) Adoption of high power HTSSOP-B20 package (BD3506EFV): 5.0 x 6.4 x 1.0 (mm)
