Description
The STEVAL-LDO001V1 board features the
following high performance low dropout linear
voltage regulators in miniature packages:
- LDBL20 200 mA high PSSR low quiescent
current in ST STAMP™ bumpless chip-scale
package
- LDLN025 250 mA low noise, low quiescent
current in Flip-Chip4
- LD39130S 300 mA ultra-low quiescent current
in DFN6L
- STLQ020 200 mA very-low quiescent current in
DFN6L
Using the quad LDO board with state-of-the-art
very low dropout voltage regulators, you can
easily evaluate performance levels in a single
set-up to choose the best design solution.
The four miniaturized LDOs are designed for
extend battery life in portable smart devices.
