Application Note

BA178xx, BA78xx Series Dropout Voltage
 
This application note provides design values of the “Dropout voltage” that are necessary for designing circuits. From the operating temperature and output current of the target specification, check the maximum value of the input/output voltage difference and use it as the circuit design value.
Basics of Linear Regulators
 
A linear regulator, also referred to as a "three-terminal regulator" or "dropper," is a power supply long known to many designers owning to its simple circuitry and ease of use...
Linear Regulator Specifications
 
Very important information such as maximum ratings, operating conditions and characteristic graphs are described in the table.
Simple Test Method for Estimating the Stability of Linear Regulators
 
Low drop-out (LDO) regulators developed back in the age when large-capacitance multi-layer ceramic capacitors (hereinafter, MLCCs) were uncommon cause a phase delay, leading to oscillation when connected to a low-ESR capacitor like an MLCC...
Reverse Voltage Protection
 
A linear regulator integrated circuit (IC) is a DC-to-DC buck converter system that reduces a DC supply from higher voltage level to a lower voltage level...
BAxxCC0 Series Circuit Using a Ceramic Output Capacitor
 
This application note proposes a circuit using an output ceramic capacitor that allows a stable phase compensation.
Power Source ON/OFF Characteristics for Linear Regulator
 
When a linear regulator IC is turned ON, the electric charge is stored in the output capacitor and the output voltage increases up to the specified value.
Problem Situations: Power Supply Does Not Start
 
Although linear regulators can be used to easily configure power supplies, the linear regulators may cause startup problems depending on the type of loads. This application note introduces cases where the power supplies do not start correctly in the linear regulators.
Table of resistance for output voltage setting on linear regulator Ics
 
This application notes provide tables for each series so that it is easy to set the resistance value for the output voltage setting from various internal reference voltages VREF.
