LP38843S-1.2 is a linear voltage regulator (PMIC) with a wide range of application fields and working principles. It is a single-chip step-down converter with integrated high side MOSFET, providing high efficiency with minimal external components.LP38843S-1.2 can operate at input voltages of up to 36V with internal current limit of up to 2A. It offers output voltage options of 1.2V, 1.1V, 1.2V, 1.25V and 1.3V, and provides load current up to 2A. Its current limit accuracy is less than ±3%. In addition to a short-circuit protection, it also features an integrated thermal-shutdown, under-voltage lockout, over-temperature protection and auto recovery functions. It supports both PWM and PFM mode operation, offering excellent response to fast load transients and high efficiency at light load. One of the major advantages of LP38843S-1.2 is its low quiescent current. With its low component count, high efficiency and excellent noise suppression, it is an ideal choice for use in portable devices and automotive applications. Its integrated power-saving feature allows for reduced switching noise and increased battery life.The working principle of LP38843S-1.2 is based on its internal current limit. When the output current drops below the current limit, the internal MOSFET starts to increase the output voltage and supply the load with a consistent voltage. If the load current increases above the current limit, the internal MOSFET switches and the voltage across the load is clamped. LP38843S-1.2 is highly suitable for automotive and portable electronic devices needing a stable voltage output. It provides high efficiency in light loads, supports both PWM and PFM mode operation, and has a low component count and minimal external component requirements. Its excellent current limit accuracy, response to fast load transients and flexible voltage output options make it an ideal choice for a wide range of applications.
