MP2000
Low Input Voltage
150mA Linear Regulator
The Future of Analog IC Technology
DESCRIPTION
The MP2000 is a low-voltage, low-dropout
bipolar linear regulator. It operates from 1.35V
to 6.0V input voltage, and regulates the output
voltage from as low as 0.5V.
The MP2000 can supply up to 150mA of load
current. The MP2000 features thermal overload
and current limit 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
θ
JA
, and the ambient temperature
T
A
. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by P
D
(MAX)=(T

(MAX)-
T

)/
θ
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.

Description
Power Source Input. IN supplies the internal power to the MP2000 and is the source of the
pass transistor. Bypass IN to GND with a 2.2μF or greater capacitor.
Ground.
Enable Input. Drive
EN
high to turn off the MP2000; low to turn it on. For automatic startup,
connect
EN
to GND.
Feedback Input. Connect a resistive voltage divider from OUT to FB to set the output
voltage. OUT feedback threshold is 0.5V.
Regulator Output. OUT is the output of the linear regulator. Bypass OUT to GND with a
2.2μF or greater capacitor.
