DESCRIPTION
The MP2005 is a micropower, ultra low-dropout
LDO linear regulator. It has a 1.0V to 5.5V input
voltage range and can regulate the output
voltage from as low as 0.5V. The MP2005 can
supply up to 800mA of load current with a
typical dropout voltage of 90mV. It requires a
bias supply (2.7V to 5.5V) separate from V
IN
to
run the internal reference and LDO drive
circuitry. The output current comes directly from
the input voltage supply for high efficiency
regulation. The 0.5V internal reference voltage
allows the output to be programmed to a wide
range of voltages (0.5V to 4V).
A low bias current of 100µA makes the MP2005
ideal for use in battery-powered applications.
The bias supply V
BIAS
can be directly applied
from the battery while V
IN
is powered from the
high efficiency buck regulator (or other
secondary supply). This reduces output noise
and the size of the decoupling capacitor.
Other features of MP2005 include thermal
overload and current limit protection, stability
with ultra low ESR ceramic capacitors as low as
1μF, and fast transient response. The MP2005
is available in a 8-pin QFN (2mm x 3mm)
package.

Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature T
J
(MAX), the junction-to-
ambient thermal resistance θ
JA
, and the ambient temperature
T
A
. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by P

. Exceeding the maximum allowable power dissipation
will cause excessive die temperature, and the regulator will go
into thermal shutdown. Internal thermal shutdown circuitry
protects the device from permanent damage.
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on JESD51-7, 4-layer PCB.
