LP38692SDX-1.8 is a Linear PMIC - Voltage Regulator integrated circuit (IC) manufactured by TI (Texas Instruments). It is part of TI’s LDO (Low Dropout Voltage) regulator family, which is specifically designed to deliver regulated voltage over a wide operating range of input voltages. The regulator operates over an extended temperature range and provides 160mA of approximate output current.

LP38692SDX-1.8 has a wide range of applications including cellular phones, photo cameras, wearable devices and automotive. It is capable of providing ultra-low quiescent current while withstanding high transient load currents and maintaining a high degree of efficiency. It also has a wide range of different output enable and disable options, making it suitable for diverse applications.

The regulator consists of a wide operating input range of 1.65V to 5.5V, and a fixed output voltage of 1.8V. It also has an internal circuitry that provides high transient current and transient voltage performance. The current limit is set internally to provide optimal protection in case of a short circuit. The IC has minimum dropout voltage of 200mV at full output current of 160mA. It also has integrated thermal protection and is available in a wide variety of output voltage options.

The working principle of the LP38692SDX-1.8 is based on the on-chip linear regulator. The IC contains an internal reference voltage, which is then compared with the voltage at the output. This comparison creates a control voltage, proportional to the difference between the voltage at the output and internally generated reference voltage. This control voltage is then used to control a series pass transistor connected to the output of the regulator.

The LP38692SDX-1.8 comes with various features and protection mechanisms for user convenience. It has programmable over-current limiter and over temperature protection. It also has a low power standby mode for applications in battery powered systems. The over-current protection feature reduces the quiescent current drawn from the battery and increases the system’s efficiency. Lastly, the device has integrated short-circuit protection which ensures that the IC will not damage the circuit if the load is shorted.

The LP38692SDX-1.8 is an extremely capable linear voltage regulator IC. Its wide range of features, over-current and over-temperature protection make it a suitable solution for many different applications. The combination of low dropout voltage, wide operating temperature range and very low quiescent current make it an ideal choice in power sensitive applications.
