SiP2211 is a dual output low dropout regulator capable of
supplying 150 mA from output 1 and 300 mA from output 2.
The SiP2211 has the outputs independently enabled. Also
the SiP2211 offers a low dropout, low ground current and
extremely low noise with the addition of a bypass capacitor.
Protection features include undervoltage lockout, output
current limit, and thermal shutdown.
The Fixed output version of SiP2211 is available in a lead
(Pb)-free MLP33-10 PowerPAK package and the adjustable
version is available in a lead (Pb)-free MLP44-16 PowerPak
package. Both packages ares specified to operate over the
range of - 40 °C to 85 °C.

Notes:
a. Room = 25 °C, Full = - 40 to 85 °C.
b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum.
c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
d. Timing is measured from 90 % of LDO #1’s final value to 90 % of LDO #2’s final value.
e. For higher output of the regulator pair.
f. Dropout voltage is defined as the input to output differential voltage at which the output voltage drops 2 % below the output voltage measured
with a 1 V differential, provided that V
IN
does not drop below 2.25 V. When V
OUT(nom)
is less than 2.25 V, the output will be in regulation when
2.25 V - V
OUT(nom)
is greater than the dropout voltage specified.
