LM1117LDX-1.8 is a low drop-out three-terminal adjustable regulator with a maximum output current of 500 mA. It can be used to provide regulated output voltage from 1.2V to 3.3V, making it suitable for numerous high current applications.

The LM1117LDX-1.8 is a high performance low dropout voltage regulator which has an output voltage accuracy of ±1.5% over the full temperature range. The device has a guaranteed input-to-output voltage differential of 1.8V and output current up to 500mA. It is available in two versions, one with an adjustable output voltage (LM1117LDX-ADJ) and the other with fixed 1.8V and 3V outputs (LM1117LDX-1.8 and LM1117LDX-3, respectively).

The LM1117LDX-1.8 belongs to the linear voltage regulator family which features low noise, low power dissipation and excellent line regulation. It is suitable for a variety of applications, including microprocessor-based systems and battery supplied systems. The regulator can be used as a power saving step-down regulator, providing appropriate current limiting and thermal protection.

The LM1117LDX-1.8 is designed to provide a regulated output voltage regardless of load current, input voltage or temperature. The internal architecture of the LM1117LDX-1.8 consists of an error amplifier, a PNP pass transistor, a voltage reference and a current source. The error amplifier compares the output voltage and the reference voltage. The output voltage is controlled by the pass transistor and a feedback loop between the pass transistor and the error amplifier.

The voltage reference provides the comparator with a preset voltage for the feedback loop. The current source ensures that the output voltage does not drift with changing temperature, line and load conditions. The current source is proportional to the reference voltage, so the output voltage changes slowly with temperature.

The LM1117LDX-1.8 can provide extremely low dropout voltages, which makes it ideal for low voltage operations. The device features low quiescent current and excellent transient response for high output currents. It also offers high PSRR, making it suitable for noise sensitive applications. The LM1117LDX-1.8 supports wide operating temperature ranges of -40°C to +125°C.

The LM1117LDX-1.8 is a highly reliable, highly accurate and cost-effective solution for many high current applications, offering excellent performance and quality. It is suitable for a wide variety of applications, including precision power supplies, LED current regulation, battery-powered systems, and audio and telecommunications equipments. Its low quiescent current and low dropout voltage ensure power savings. The device is also protected by over temperature, voltage and current protection, making it ideal for high reliability systems.
