3-Terminal Regulators
The fixed output models are produced as an equivalent lineup to the μA7800
Series of industrial-standard fixed positive voltage output power supply
regulators developed by Fairechild in 1976.
Output voltages of 5 V, 6 V, 7 V, 8 V, 9 V, 10 V, 12 V, 15 V, 18 V, 20 V and 24 V
are available. Output voltage tolerance is within 4%. Three output currents 1 A
(BA78xx), 500 mA (BA78Mxx) and 100 mA (BDxxFA1) are available. An approx.
2 to 3 V difference in I/O voltage is required. The lineup does not include
equivalents to the μA7900 Series’ fixed negative voltage output power supply
regulators.
Naming rules
The variable output models are produced as an equivalent lineup to the LM1117,
a low saturation output version of the industrial-standard LM317 released by
National Semiconductor Corporation in 1977. The difference in I/O voltage
follows the LDO specification, by ranging from 2 V to 1.2 V as before. The output
voltage range is from 1.25 V to 8.6 V and output voltage tolerance is within 1%.
Output voltage is 1 A.

Single-Output LDO Regulators 45 V, 50 V rating
The left figure shows a system diagram of 45 V and 50 V rated LDO
type linear regulators. These low quiescent current regulators
feature the following specifications: an output voltage tolerance
within 2% across the entire temperature range, output current of
200 mA or 500 mA, and current consumption of 6 μA to 80 μA. The
small amount of quiescent current is suitable for reducing current
consumption in systems directly connected to batteries. The
BD7xxL2 and BD7xxL5 Series realize an ultra-low quiescent current
of 6 μA, further contributing to a reduction in current consumption.

This Series of ultra-LDO type linear regulators uses L3RegTM technology, which provides solutions for power supply systems requiring multiple low voltage patterns such as a digital signal
processing LSIs. The ultra-LDO type offers excellent low input voltage operation and low I/O voltage characteristics that ensure great efficiency comparable with a switching regulator. This
also allows a reduction in external parts such as inductors.

The lineup includes the BD4269FJ, BD4269EFJ and BD4275
that integrate a voltage detector function. These models are
useful for monitoring for abnormal voltages. The lineup includes
the BD4271, BD3010AFV, BD3020HFP and BD3021HFP that
integrate a watchdog timer/voltage detector circuit. These
models are useful for monitoring for malfunctions and abnormal
voltages of microcontrollers.

Microcontroller Monitoring Power Supply Solutions
Product example: BD3010AFV, BD3020HFP, BD3021HFP
Ultra-low quiescent current: 80µA (Typ)
Output transistor: Pch DMOS low saturated type
Maximum rated voltage: 50V
Output current: 200mA , 500mA
Output voltage: 5.0V 2%
(Across the entire temperature range)
A low ESR ceramic capacitor is available for output phase compensation.
The built-in watchdog timer monitors for microcontroller hang-ups and
resets the microcontroller in the event thereof, which enables the system
to restart automatically.
The watchdog timer is automatically turned ON/OFF depending on the
load current so as to avoid unnecessary monitoring by the timer when the
microcontroller is in the sleep mode (BD3010).
Forced ON/OFF control enables the watchdog timer to stay OFF until the
system is stable, e.g., when the microcontroller (BD3010, BD3021) starts
up, etc.
The built-in undervoltage output reset (power-on reset) circuit enables
setting of the actuation delay time.
The reset detection voltage is adjustable (BD3010, BD3020).
The built-in output current control circuit prevents damage to the IC by
output short-circuiting.
The built-in thermal shutdown circuit prevents thermal damage to the IC if
overloaded.
The BD3010AFV, BD3020HFP and BD3021HFP are regulators with a rated voltage of 50 V and output current of 200 mA/500 mA. They are power supply ICs that integrate a watchdog
timer (WDT) that monitors for microcontroller malfunctions and a reset circuit that monitors power supply voltage on a single chip.

Support of JEDEC DDR1/2/3/3L
Product example: BD35395FJ-M
The BD35395FJ-M is a terminal regulator that
supports DDR1/2/3/3L SDRAMs in conformity with
JEDEC. It integrates a VTT power supply, one of the
three power supplies required for the DDR memory.
VTT output is a linear power supply that integrates
an N-MOSFET and is capable of supplying a
maximum 1 A both to the sink and source. The
internal OP-AMP designed for high-speed operation
helps realize excellent transient response
characteristics. To drive the internal N-MOSFET, a
bias power supply of 3.3 V or 5.0 V is required. This
linear regulator possesses an independent standard
input pin (VDDQ) and an independent feedback pin
(VTTS) in order to keep the JEDEC-specified voltage
precision, and contribute to excellent output voltage
precision and load regulation.BD35395FJ-M Application Circuit

A DDR memory needs three power supplies. For
VDDQ, a power supply to drive the memory cell, high-
speed load response and voltage precision are
required in order to assure reliability in memory
operations. Input to the memory cell is judged based
on VREF, which is one-half of VDDQ voltage.
Although the required current value is small, voltage
precision is required in response to changes in VDDQ
voltage. VTT is the termination voltage of the memory
output, which terminates the memory output via a
terminal resistor RT. Its voltage is one-half of VDDQ
and is required to follow changes in VDDQ voltage like
VREF. As the memory output switches to High or Low,
the output current must be capable of following the
source or sink operation at a high speed.
Input voltage range: 2.7V to 5.5V
Output current: 1A
