DESCRIPTION
The MP8802 is a low-noise, low-dropout linear
regulator. It operates from 2.7V to 6.5V input
voltage, and regulates the output voltage with
2% accuracy at 2.5V, 2.85V, 3.3V, or from
1.25V to 5V.
The MP8802 can supply up to 250mA of load
current. The MP8802 features thermal overload
protection. It is available in a 5-pin TSOT23-5
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
JA
, and the ambient temperature
T
A
. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by P
D
(MAX)=(T
J
(MAX)-
T
A
)/
JA
. 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..
