UC1544J - Brand New IC Chips
-
Description
The UC1544J is a linear low-dropout (LDO) regulator with a split-supply architecture. It has separate bias and supply inputs, which allows bias to be taken directly from the battery, while the input is taken from a lower preregulated source. This design enables a smaller differential voltage between input and output, resulting in greater efficiency over a wider VBAT range. The UC1544J comes in a fixed-voltage output, 5-bump, WLCSP package.

The UC1544J is a versatile linear low-dropout regulator. Its main advantage is its split-supply architecture, which allows for greater efficiency over a wider VBAT range. It also has a small form factor and offers a range of fixed voltage options. However, it has a relatively low output current compared to some other regulators on the market.
