MIC39150/39151
1.5A Low-Voltage Low-Dropout Regulator
General Description
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. Utilizing
Micrel’s proprietary Super
β
eta PNP pass element, the
MIC39150/1 offers extremely low dropout (typically 375mV at
1.5A) and low ground current (typically 17mA at 1.5A).
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. A guaranteed
maximum dropout voltage of 500mV over all operating con-
ditions 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. The
MIC39150/1 also has fast transient response for heavy
switching applications. This device requires only 10
μ
F 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, reversed-
lead 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.
For applications requiring input voltage greater than 16V or
automotive load dump protection, see the MIC29150/1/2/3
family.
