The MIC2954-08BM-TR is a linear voltage regulator from Microchip. This device, part of their PMIC (Power Management Integrated Circuit) series, is designed for cost sensitive and low-power point-of-load (POL) solutions. It features ultra low dropout (LDO) with an output voltage range as low as 0.9 V, high accuracy, fast transient response, and current limiting. In addition, it has a low quiescent current and high efficiency, making it ideal for consumer and industrial applications.

The MIC2954-08BM-TR is capable of supplying up to 800 mA with a dropout voltage of only 100 mV at full current. It provides a wide input voltage range of up to 24 V, enabling it to be used in a variety of applications. Furthermore, it features integrated current and thermal protection and a low-power shutdown mode for improved system operation. The device is housed in a small package, and is available in a variety of output voltage options to suit different application needs.

This device is designed with flexibility in mind, allowing the user to optimize power consumption while limiting the number of external components. It provides adjustable output voltage, enabling the user to select the right output voltage for each application. Furthermore, it includes integrated under-voltage lockout, which prevents operation with an insufficient input voltage and current limit protection, which protects against overloads, making it safer and more reliable.

The MIC2954-08BM-TR utilizes a resistive divider, consisting of two resistors, R1 and R2, to choose the appropriate output voltage. The voltage on the output pin is determined by V_OUT = V_IN x (R1 / (R1 + R2). The output voltage is adjustable from 0.9 V to 24 V, making it suitable for a variety of output voltages for a number of different applications. Thanks to the low dropout voltage, the MIC2954-08BM-TR is able to maintain high efficiency and low power consumption. The device also supports a wide operating temperature range of -40C to +125C.

In addition, the MIC2954-08BM-TR features a low-power shutdown mode which can be used to reduce current consumption in standby mode. Its integrated thermal protection circuit prevents device damage due to overtemperatures. Furthermore, it provides a power-good (PG) flag which indicates when the output voltage has been regulated within a certain range. This flag feature helps reduce the number of components needed by eliminating the need to integrate additional monitoring circuitry.

The MIC2954-08BM-TR is a versatile and cost-effective voltage regulator ideal for various POL applications. Its adjustable output voltage, low dropout, high accuracy, and integrated protection features make it an attractive option for end users seeking improved efficiency and reliability. Additionally, its small form factor and wide operating temperature range make it a suitable fit for space-constrained systems.
