LP87332BRHDTQ1 is a power management integrated circuit (PMIC) used to efficiently regulate and manage the supply of power to a given electrical circuit or system. These components are used for linear and switched voltage regulation, as well as for supplying power to multiple sub-circuits within a larger electrical system or device. The LP87332BRHDTQ1 power management integrated circuit is commonly used in consumer electronic devices such as laptops, tablets, and smartphones.

The LP87332BRHDTQ1 can provide accurate regulation of a wide range of voltages, from 3.3V to 28V. The device has a very low quiescent current of just 1.5μA, making it well-suited to applications where power consumption must be minimized. The LP87332BRHDTQ1 includes a high-current regulated output voltage for two sub-circuits and two low-current regulated output voltage pins for three other sub-circuits. The device is both low-noise and fast-response, making it suitable for use in both linear and switched power regulation systems.

The LP87332BRHDTQ1 achieves its excellent regulation performance by utilizing a hysteretic control scheme with an on-chip feedback network to accurately monitor and regulate the output voltage of each sub-circuit. This scheme is fast-responding and highly-efficient, resulting in very tight output voltage stability and accuracy. The controlled output voltages can be adjusted through changing the input voltage or via the external negative temperature coefficient (NTC) thermistor. This thermistor can be used to adjust the output voltage according to operating environment changes.

Like other LP87332BRHDTQ1 PMICs, the LP87332BRHDTQ1 provides protection against both over-current and over-temperature events. Over-current protection is handled by the on-chip current limit circuits, while over-temperature protection is enabled through the adjustable external NTC thermistor. This protection is both fast-acting and highly reliable, ensuring that the LP87332BRHDTQ1 is suitable for use in even the most demanding power management applications.

In summary, the LP87332BRHDTQ1 PMIC is a versatile, low-quiescent current power management integrated circuit suitable for a wide range of linear and switched voltage regulation applications. Its features, such as fast response, low noise, and very high accuracy, make it an excellent choice for power regulation and management of a variety of consumer electronic devices.
