MIC39152 Datasheet | Micrel Semiconductor

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 ponents. Utilizing Micrel’s proprietary Super βeta PNP® pass element, the MIC39150/1/2 offers extremely low dropout (typically 375m V at 1.5A) and low ground current (typically 17m A 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 500m V 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 patible 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 es 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 es in 5-Pin, TO-263 (D2Pak) and TO-252 (D-Pak) packages. For applications requiring input voltage greater than 16V or automotive load dump protection, see the MIC29150/1/2/3 family.
