MIC39500/39501
5A μCap Low-Voltage Low-Dropout Regulator
General Description
The MIC39500 and MIC39501 are 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
MIC39500/1 offers extremely low dropout (typically 400mV
at 5A) and low ground current (typically 70mA at 5A).
The MIC39500/1 is ideal for PC Add-In cards that need to
convert from standard 2.5V or 3.3V, down to new, lower
core voltages. A guaranteed maximum dropout voltage of
500mV over all operating conditions allows the MIC39500/1
to provide 2.5V from a supply as low as 3V or 1.8V from
2.5V. The MIC39500/1 also has fast transient response, for
heavy switching applications. The device requires only 47μF
of output capacitance to maintain stability and achieve fast
transient response
The MIC39500/1 is fully protected with overcurrent limiting,
thermal shutdown, reversed-battery protection, reversed-
lead insertion protection, and reversed-leakage protection.
The MIC39501 offers a TTL-logic-compatible enable pin and
an error ? ag that indicates undervoltage and overcurrent
conditions. Offered in a ? xed voltages, 1.8V and 2.5V, the
MIC39500/1 comes in the TO-220 and TO-263 packages
and an ideal upgrade to older, NPN-based linear voltage
regulators.
For applications requiring input voltage
greater than 16V, see the
MIC29500/1/2/3 family. For applications
with input voltage 6V or below, see
MIC3750x LDOs.
