The SiP2214 is a dual output low dropout regulator capable
of supplying 150 mA from output 1 and 300 mA from output
2. In addition to the LDOs, an open drain output has been
included, which is capable of sinking 150 mA. The SiP2214
offers a low dropout, low ground current and extremely low
noise with the addition of a bypass capacitor.
Protection features include POR with adjustable delay,
undervoltage lockout, output current limit, and thermal
shutdown.
The fixed output version of SiP2214 is available in the
MLP33-10 PowerPAK package and the adjustable version is
available in the MLP44-16 PowerPAK package. Both
packages are specified to operate over the range of - 40 °C
to 85 °C.

Notes:
a. Room = 25 °C, Full = - 40 °C 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. Guaranteed by design.
f. For higher output of the regulator pair.
g. 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.
