STMicroelectronics reveals low-noise low-voltage regulator for energy-conscious applications

瀏覽次數:330

Taiwan, Jun 22, 2022 – STMicroelectronics’ LD56020 200mA low-dropout voltage regulator operates with a supply from 1.1V to 5.5V and has low output noise for applications that demand excellent stability and long battery runtime.

Ideal for mobiles, vision sensors, and wireless modules, the competitively priced LD56020 has extremely low dropout voltage of just 190mV (max. at full load) and maximum quiescent current of 25μA at light load. An external enable pin permits control logic to put the regulator into standby mode, which reduces current below 0.1μA.

With supply-voltage rejection (SVRIN) of 90dB (1kHz, 20mA) and output noise of just 8.8μVRMS (10Hz to 100kHz), the LD56020 provides a clean power rail for low-voltage digital circuitry. The circuit is stabilized with only one small ceramic capacitor at each of the input and output terminals. In addition to minimizing the bill of materials, the low overall component count combines with the regulator’s tiny chip-scale package (CSP) outline of 0.65mm x 0.65mm to ensure a compact circuit footprint with low impact on PCB size.
