Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ (MAX), the junction-toambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by PD (MAX) = (TJ
(MAX)-TA)/θJA. 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.

Figure 1—Functional Block Diagram
The MP2016 is a linear regulator designed
primarily for high input voltage applications. The
MP2016 has an output that is adjustable from
1.2V to 40V with a simple resistor divider. The
maximum power output current is a function of
the package’s maximum power dissipation for a
given temperature.
The MP2016 uses external feedback, allowing
the user to set the output voltage with an external
resistor divider. The typical FB pin threshold is
1.23V.
The IC enters shutdown mode when SHDN is
low. In shutdown mode, the pass transistor,
control circuitry, reference and all biases turn off,
reducing the supply current to <2µA. Connect
SHDN to IN for automatic startup.
MP2016 Rev.1.0
10/10/2011
The peak output current is limited to 50mA, which
exceeds the 30mA recommended continuous
output current. The output can be shorted to
ground for 30 seconds without damaging the part.
When the junction temperature is too high, the
thermal sensor sends a signal to the control logic
that will shutdown the IC. The IC will restart when
the temperature has sufficiently cooleds.
The maximum power dissipation is dependent on
the thermal resistance of the case and the circuit
board, the temperature difference between the
die junction and the ambient air, and the rate of
air flow. The GND pin and Exposed Pad must be
connected to the ground plane for proper
dissipation.

APPLICATION INFORMATION
COMPONENT SELECTION
Setting the Output Voltage
Set the output voltage of the MP2016 by using a
resistor divider as shown:
OUT 3
VOUT
Output Noise
The MP2016 will exhibit noise on the output
during normal operation. This noise is negligible
for most applications. However, in applications
that include analog-to-digital converters (ADCs)
of more than 12 bits, one needs to consider the
ADC’s power supply rejection specifications.
The feed forward capacitor C3 across R1 will
significantly
reduce
the
output
noise.
MP2016
FB 4

Figure 2—MP2016 with External Resistor
Divider
Choose R2=250kΩ to maintain a 5µA minimum
load. Calculate the value for R1 using the
following equation:
⎛ V
⎞
R1 = R2 × ⎜ OUT − 1⎟
⎝ 1.23V
⎠
Input Capacitor
For proper operation, place a ceramic capacitor
(C1) between 1µF and 10µF of dielectric type
X5R or X7R between the input pin and ground.
Larger values in this range will help improve line
transient response.
Output Capacitor
For stable operation, use a ceramic capacitor (C2)
of type X5R or X7R between 1µF and 10µF.
Larger values in this range will help improve load
transient response and reduce noise. Output
capacitors of other dielectric types may be used,
but are not recommended as their capacitance
can deviate greatly from their rated value over
temperature.
To improve load transient response, add a small
ceramic (X5R, X7R or Y5V dielectric) 22nF feed
forward capacitor in parallel with R1. The feed
forward capacitor is not required for stable
operation.
