DESCRIPTION

The SiP2213 is a dual output low dropout regulator capable of

supplying 150 mA from output 1 and 300 mA from output 2. In

the SiP2213, the outputs are sequenced at power on. The

output of LDO #1 has to settle before the output of LDO #2

begins turning on. In addition to the LDOs, an open drain

output has been included, which is capable of sinking 150 mA.

The SiP2213 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 SiP2213 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.
