Micrel MIC39150

The MIC39150 and MIC39151 are 1.5A low-dropout linear voltage regulators that provide a low voltage, high current output with a minimum of external components. The MIC39150/1 is ideal for PC add-in cards that need to convert from 3.3V to 2.5V or 2.5V to 1.8V. The MIC39150/1 also has fast transient response for heavy switching applications.

GENERAL DESCRIPTION

Utilizing Micrel’s proprietary Super βeta PNP™ pass element, the MIC39150/1 offers extremely low dropout (typically 375mV at 1.5A) and low ground current (typically 17mA at 1.5A). A guaranteed maximum dropout voltage of 500mV over all operating conditions allows the MIC39150/1 to provide 2.5V from a supply as low as 3V or 1.8V from a supply as low as 2.3V. This device requires only 10µF of output capacitance to maintain stability and achieve fast transient response The MIC39150/1 is fully protected with overcurrent limiting, thermal shutdown, reversed-battery protection, reversedlead insertion, and reverse-leakage protection. The MIC39151 offers a TTL-logic compatible enable pin and an error flag that indicates undervoltage and over current conditions. Offered in fixed voltages of 2.5V and 1.8V, the MIC39150/1 comes in the TO-220 and TO-263 packages and is an ideal upgrade to older, NPN-based linear voltage regulators.
