MIC39150/39151/39152
1.5A, Low-Voltage Low-Dropout
Regulator
General Description
The MIC39150, MIC39151, and MIC39152 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 βeta
PNP® pass element, the MIC39150/1/2 offers extremely low dropout (typically 375mV at 1.5A) and low ground current (typically 17mA at 1.5A).
The MIC39150/1/2 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 MIC39150/1/2 exhibit fast transient response for heavy switching applications and requires only 10µF of output capacitance to maintain stability and achieve fast transient response.
The MIC39150/1/2 is fully protected with current limiting, thermal shutdown, reversed-battery protection/lead insertion, and reverse-leakage protection. The MIC39151 offers a TTL-logic compatible enable pi...
