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.
