Description

This is 1A Low Dropout Positive Voltage Regulator. A voltage regulator is an electronic device that is used to maintain a constant voltage level, regardless of changes in load or input voltage.

It does this by adjusting the output voltage so that it remains within a specified range.

This helps to ensure that the voltage supplied to a device remains within the acceptable range, even under varying conditions such as changes in temperature or load.

1. LD1117A is a three terminal low dropout positive voltage regulator with a dropout of
1.15V at 1A output current.

2. Regulator is available in an adjustable version which can set the output voltage 1.25V to 12V with only 2 external resisitors.In addition,it is also available in 7 Fixed output
voltages: 1.2V, 1.5V, 1.8V, 2.5V, 2.85V, 3.3V an 5.0V.

3. LD1117 provides current limiting and thermal shutdown. Its circuit includes a trimmed Bandgap reference to assure output voltage accuracy to be within ±1.0% for fixed output
voltage version and ±2.0% for adjustable output voltage version. Current limit is trimmed to ensure specified output current and controlled short-circuit current. On-chip thermal
shutdown provides protection against any combination of overload and ambient temperature that would create excessive junction temperature

Description

The APL5607, APL5607A is a low quiescent current and low dropout linear regulator which is designed to power a DC fan and deliver up to 600mA output current. The output voltage follows the 1.6 times of VSET voltage and typical dropout voltage is only 220mV (typical) at 600mA output current.

This is a type of voltage regulator integrated circuit (IC) that is designed to provide a stable and regulated output voltage with a maximum output current capacity of 600 milliamperes (mA). Linear regulators are commonly used in electronic circuits to maintain a constant voltage level despite variations in input voltage and load current.
