MIC39150-2.5BU Description

Short technical summary and product information.

The MIC39150-2.5BU from Micrel Inc. is a 1.5A low-voltage, low-dropout (LDO) linear voltage regulator designed for high-current applications requiring a stable output. It utilizes a proprietary Super βeta PNP pass element to achieve low dropout voltage, typically 375mV at 1.5A, and a guaranteed maximum of 500mV over all operating conditions.

This regulator provides a fixed 2.5V output with 1% initial accuracy and is ideal for converting higher voltages like 3.3V down to 2.5V. It features fast transient response and requires only a small 10µF output capacitance for stability. The device includes comprehensive protection circuitry, including current limiting, thermal shutdown, reversed-battery protection, and reverse-leakage protection.

The MIC39150-2.5BU is offered in a TO-263 (D2Pak) surface-mount package, making it suitable for space-constrained designs. Its robust protection features and stable performance make it a good choice for low-voltage digital ICs, PC add-in cards, and low-voltage microcontroller power supplies.
