Description
The STEVAL-ISB034V1 board features the
LDBL20 high performance linear voltage
regulator, configured to convert a 2.85 V to 5.5 V
DC input voltage into a precise and stable 2.5 V
output voltage.
Only two small ceramic capacitors are needed to
implement the linear regulator solution.
The very low dropout LDBL20 voltage regulator
features high PSRR, low quiescent current and
the minute ST Stamp™ chip-scale package, with
a footprint of only 0.47 x 0.47 mm².
It is designed for low power battery-operated
equipment like smartphones, tablets and
wearable devices.
