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 β eta 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 (D 2 Pak)
packages. The MIC39152 adjustable option allows
programming the output voltage anywhere between 1.24V
and 15.5V and comes in 5-Pin, TO-263 (D 2 Pak) and
TO-252 (D-Pak) packages.
