A flexible power management solution to design your project quickly and efficiently

The STEVAL-QUADV01 evaluation board is a versatile tool based on different step-down regulators: the L6981, L7983, ST1PS03, and the ST730 LDO. These regulators offer a range of features and capabilities that make the board suitable for a wide range of applications.

The board offers four distinct approaches for generating a 5 V output voltage, which can be conveniently adjusted to alternative values by modifying the resistors in the feedback networks' resistive dividers.

To simulate and configure the L6981, L7983, and ST1PS03 step-down converters, you can use the eDesignSuite and eDSim software tools. It enables you to optimize the performance of the regulators meeting the specific needs of your application, before verifying the results on the evaluation board.

Ultra-tiny low-dropout regulator in breakthrough bumpless chip-scale package

The LDBL20 is a powerful 200 mA LDO in a tiny 0.47 x 0.47 mm innovative ST STAMP™ chip-scale package. The input voltage can range from 1.5 to 5.5 V, with 200 mV typical dropout. Rejection (PSRR) of 80 dB at 100 Hz and 50 dB at 100 kHz simplifies filtering over a wide frequency range to provide a stable rail for low-power circuitry in battery-operated applications. Quiescent current of 20 µA no-load, 100 µA full-load, and 0.3 µA in standby help maximize efficiency under all operating conditions.
