The LDL1117S18R is a versatile and reliable low-dropout (LDO) regulator that is suitable for a variety of applications. It is an ideal linear regulator for voltage regulation in low-power applications, such as battery-powered electronic devices, small handhelds, sensor circuits, and automotive applications. The regulator is integrated with an over temperature protection circuit that monitors the die temperature, allowing it to maintain a constant output voltage even at extreme temperatures.

The LDL1117S18R is a three-terminal adjustable output voltage regulator. The output voltage is set with a single resistor from the adjustment pin to ground—typically from 0.8V to 19V. The device also features excellent line and load regulation and fast transient response. The low on-resistance of the LDO ensures a low supply current and a regulator with a very low dropout at full load.

The regulator provides excellent ripple rejection and fast transient response. The output voltage can be stabilized by decreasing the external capacitor size at the same time ensuring high peak current capability and excellent line and load regulation. The device has a fast transient response to line transients, making it well suited for applications where a low cost device is needed to provide a stable output.

The LDL1117S18R can operate over a wide input voltage range of 1.2V to 19V and has an adjustable output voltage range of 0.8V to 19V. The device is available in a variety of package sizes and has a maximum supply current of 100mA. The LDO has an enable pin to save power when not in use and also features an over-temperature protection circuit that monitors the die temperature, allowing it to maintain a constant output voltage even at extreme temperatures.

The LDL1117S18R is a versatile and reliable low-dropout (LDO) regulator that is suitable for a variety of applications such as low-power, small handheld, sensor circuits, and automotive applications.
