KIA1117API00 overview

The KIA1117API00 is an Adjustable Voltage Regulator, supplied in a TO-220IS Type package. Main ratings: Low Dropout Voltage 1.1V/Typ. (Iout=1.0A); Very Low Quiescent Current 2.5 /Typ.; Adjustable Version Availability Vref=1.25V; High Ripple Rejection 80dB/Typ. The absolute maximum ratings table on this page lists the 6 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the KIA1117API00 key specifications and maximum ratings, with the full datasheet PDF to preview below or download.

The KIA1117API00 is a Low Drop Voltage Regulator able to provide up to 1A of output current, available even in adjustable version (Vref=1.25V).

An adjustable voltage regulator is an electronic device that provides a stable and adjustable output voltage from a varying input voltage. It is commonly used in electronic circuits to ensure that sensitive components receive a constant and regulated voltage, regardless of fluctuations in the power supply.

The main function of an adjustable voltage regulator is to maintain a specific output voltage, even when the input voltage changes. It accomplishes this by employing a control circuit that monitors the output voltage and adjusts the internal circuitry to maintain the desired voltage level.
