until the system is stable, e.g., when the microcontroller (BD3010,
BD3021) starts up, etc.

The left figure shows a system diagram of standard 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
(BD178xx), 500 mA (BD178Mxx) 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 Seriesʼ fixed negative voltage output power supply regulators.

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.

The above 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. 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.

characteristics, implementing redundant and fire prevention designs, and utilizing backups and failsafe
procedures. ROHM shall have no responsibility for any damages arising out of the use of our Poducts
beyond the rating specified by ROHM.
4.
Examples of application circuits, circuit constants and any other information contained herein are
provided only to illustrate the standard usage and operations of the Products. The peripheral
conditions must be taken into account when designing circuits for mass production.
5.
The technical information specified herein is intended only to show the typical functions of and
examples of application circuits for the Products. ROHM does not grant you, explicitly or implicitly, any
