LDO - ROHM -Macnica

Product Summary

LDO is an abbreviation for Low Drop Out, and refers to a linear regulator that operates even with a low potential difference between the input and output, and is translated as a low saturation linear regulator.
ROHM's LDO has a wide lineup of general-purpose 3-terminal regulators, low power consumption, large current, and high withstand voltage, and contributes to the power supply circuits of mobile phones, automobiles, home appliances, consumer products, and industrial equipment.

Product features

In recent years, high efficiency has become an essential requirement for electronic equipment, and switching power supplies have become mainstream in equipment that requires large output power. is a power supply that can be used anywhere.

Linear regulators are classified according to the characteristics of the manufacturing process, including bipolar process type, CMOS type, and Bi-CDMOS process type that combines the features of bipolar and CMOS. For ROHM products, you can tell which manufacturing process has the characteristics of the product by the product name, as shown below.

shape name	manufacturing process	General features
Baxxxx	Bipolar	Many have high withstand voltages such as 35V and 50V, but consume a large current of several mA.
Buxxxx	CMOS	Recently, there are high withstand voltage products such as 20V, but most of M are designed for input voltage up to 5V. However, current consumption is very small at several μA
BDxxxx	Bi-CDMOS	Combining the features of bipolar and CMOS, with 50V withstand voltage and current consumption of several μA
