The UA78L12ACD belongs to a family of Positive Voltage Linear Regulators meant for general-purpose use and is part of a larger family of PMIC products. It is a competitively priced, high performance single fixed output device providing up to 1.5A of output current.

A major application field of the UA78L12ACD is as a part of battery management systems. It offers excellent power efficiency and a wide input voltage range (2.0V - 22V) that makes it a reliable choice for ensuring battery performance and optimizing power delivery systems.

In terms of specifications, the UA78L12ACD boasts of an ultra-low input-output differential of 3V, an ultra-low dropout voltage of 200mV, an ultra-low output ripple of 1/3 of a peak-to-peak (1Vpp), and an output capacitance range of 100 – 2200µF.

The UA78L12ACD Regulator also features low quiescent current, error amplifier compensation for improved stability, and foldback current limiting with thermal protection ensuring a safe level of operation. It is available in a wide range of package options making it ideal for a variety of applications.

Considering the working principle, the UA78L12ACD Voltage Regulator consists of series pass elements designed to keep the output voltage of a power supply well regulated. The series pass elements acts as a variable resistor which reduces voltage to the desired output voltage as it works in conjunction with an error amplifier.

The amplifier amplifies the deviation of the voltage between the output and the reference voltage. This amplifies the deviation is used to adjust the series resistance of the pass elements accordingly. A feedback loop is completed by the output voltage being regulated to match the reference voltage.

In addition to the error amplifier, the UA78L12ACD Voltage Regulator also features an on-chip control circuit to control voltage regulation based on the minimum guaranteed dropout voltage. This ensures the accuracy of voltage regulation in the sense that it stops the output voltage from dropping below a certain point, even when the load current is low.

The UA78L12ACD is highly reliable and offers excellent noise performance and transient response. It also supports operation in temperatures ranging between -40℃ and +125℃ making it suitable for a wide range of temperature environments as well.

Overall, the UA78L12ACD Voltage Regulator is an economical and reliable solution for specialized applications that require a flexible and robust power delivery within the range of 2.0V - 22V.
