MIC39150-1.8WU

The MIC39150 are 1.5A LDO voltage regulators that provide a low voltage, high current output with a minimum of external components. Utilizing Micrel’s proprietary Super ßeta PNP® pass element, the MIC39150 offers extremely low dropout (typically 375mV at 1.5A) and low ground current (typically 17mA at 1.5A). The MIC39150 are ideal for PC add-in cards that need to convert from 3.3V to 2.5V or 2.5V to 1.8V with a guaranteed maximum dropout voltage of 500mV over all operating conditions. The MIC39150 exhibit fast transient response for heavy switching applications and requires only 10µF of output capacitance to maintain stability and achieve fast transient response. The MIC39150 is fully protected with current limiting, thermal shutdown, reversed-battery protection/lead insertion, and reverse-leakage protection. Offered in fixed voltages of 2.5V, 1.8V and 1.65V, the MIC39150 comes in the TO-220 and TO-263 (D2 Pak) packages.
