Automobilbau 500 mA Spannungserfasser - BD3925HFP-C

Dieser Regelkreis dient als Spannungs-Tracker für den Einsatz im Automobilbereich und verfügt über eine hohe Spannungsfestigkeit bis 50 V. Er bieten eine Ausgangs-Strombelastung von 500 mA, während der Ruhestrom auf 45 μA (typ.) begrenzt ist, so dass er für Systeme geeignet ist, die permanent an die Autobatterie angeschlossen sind und einen geringen Stromverbrauch erfordern. Der Offset beträgt ± 15 mV (für 5 V am Ausgang; 6 V

Very important information such as maximum ratings, operating conditions and characteristic graphs are described in the table.

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...

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...

Thermal Calculation for Linear Regulator

The loss in linear regulators increases as the difference between the input and output voltages increases. Since most of the loss is converted to heat, a very large amount of heat may be generated in some conditions...

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.
