The LP38858T-1.2 is a low-dropout, low-power, linear voltage regulator of FlatPak Form Factor (FF) intended for low-voltage, single output with one adjustable and one fixed output versions. It is the ideal choice for high current applications. The device is capable of delivering 1.2A adjustable output current.

The LP38858T-1.2 offers excellent line and load regulation as well as useful features such as ultra-low quiescent current, low output voltage noise, and over-temperature protection. It also features an excellent PSRR and transient response.

Applications of the LP38858T-1.2 include industrial, consumer and automotive applications such as audio amplifiers, LED drivers, power supplies, power management and voltage regulation. The LP38858T-1.2 is designed to deliver total output power of up to 1.2A when powered by 1.8V to 6V input and output voltages ranging from 0.6V to 5V.

The working principle of the LP38858T-1.2 is relatively simple. The device is a low dropout (LDO) linear voltage regulator that uses a power transistor to convert the input voltage to a regulated output voltage. The LP38858T-1.2 uses a sophisticated amplifier circuit design to provide a fast response and accurate regulation. It also features a built-in frequency compensation network that ensures that the device is stable under all operating conditions.

The LP38858T-1.2 also features a wide input voltage range of 1.8V to 6V, adjustable output current up to 1.2A and low quiescent current of 450uA. The device has an output voltage accuracy of ±1.3% and a PSRR of 82dB at 1KHz. It also provides a very low dropout of 180 mV at 0.1A. In addition, the LP38858T-1.2 provides protection against over-temperature, over-current and reverse polarity on the output side.

The LP38858T-1.2 is an excellent choice for applications where low power and high accuracy are essential. It operates over a wide temperature range of -40°C to +125°C and is available in a 3mm x 3mm package. This makes it suitable for a wide range of industrial, consumer and automotive applications.
