The LP5912Q1.2DRVTQ1 is an integrated low-noise linear regulator designed for low-current applications with high-precision output voltage accuracy. As part of the PMIC (Power Management IC) family, the LP5912Q1.2DRVTQ1 provides a cost effective, low-noise alternative to bulky and expensive power supply solutions. With a wide range of applications, this voltage regulator is suitable for a variety of applications including industrial, automotive, and consumer applications, as well as for microprocessor cores, FPGA cores, and a variety of other low-current devices.

The LP5912Q1.2DRVTQ1 can operate in a typical operating range of 1.2V–3.3V output voltages, a 0.05–1.0A continuous output current, a 0.75–1.2V dropout voltage and a unique voltage regulation accuracy of ±3mV for outputs as low as 1.2V. It also has low fluctuation of output voltage, low quiescent current (typical 0.22mA) and high efficiency. This ensures the device is highly energy efficient even at the lowest output voltage.

The LP5912Q1.2DRVTQ1 is a two-terminal, regulator-based device that sets the output voltage and current from an externally applied voltage. This voltage regulator requires two external resistors to set the output voltage and supply the current limiting and compensation. The output voltage is then set by the feedback resistor, which adjusts the feedback voltage for the regulator, responding to the control source voltage. The regulator is also responsible for sinking or sourcing current as required to maintain the desired output voltage.

The LP5912Q1.2DRVTQ1 operates with a wide input voltage range, from 4.5V to 40V, and can provide a large output current capacity of up to 1A. It is designed to handle high power dissipation, with a typical junction temperature range of -40°C to +125°C. The LP5912Q1.2DRVTQ1 is also equipped with thermal shutdown and various protection circuits, such as weak line protection, overvoltage protection and over current protection, to ensure that it operates within its rated ratings and to protect it from sudden voltage changes or overloads.

The linear regulators in the LP5912Q1.2DRVTQ1 family are highly reliable and feature an Enhanced Stable Regulated Voltage (ESRV) technology that helps maintain a very accurate output voltage over a wide temperature range and transient load conditions at all output voltages. This makes them suitable for applications that require accurate and stable output voltages with minimal power consumption.

In addition to its high efficiency, energy savings and sophisticated protection features, the LP5912Q1.2DRVTQ1 also features an integrated Glitch Guard™ function that eliminates current surges during startup. High temperature operation is also supported, with a shutdown protection temperature at +150°C, making the LP5912Q1.2DRVTQ1 well-suited for operation in harsh environments.

The LP5912Q1.2DRVTQ1 is designed to deliver extremely accurate voltage outputs, with a minimum load of 10A and a maximum output of 1A. It is ideally suited for low-noise and low-power applications that require high precision and stability. With its high reliability, low quiescent current, excellent power efficiency and wide operating temperature range, the LP5912Q1.2DRVTQ1 is an ideal choice for a variety of voltage regulation needs.
