MIC39150-2.5WU

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 proprietary Super Beta 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 pin and an error flag that indicates undervoltage and overcurrent conditions. Offered in fixed voltages of 2.5V, 1.8V and 1.65V, the MIC39150/1 comes in the TO- 220 and TO- 263 (D²Pak) packages. The MIC39152 adjustable option allows programming the output voltage anywhere between 1.24V and 15.5V and comes in 5- Pin, TO- 263 (D²Pak) and TO- 252 (D- Pak) packages.
