Ideal for mobile devices, vision sensors and wireless modules, the competitively priced LD56020 has an extremely low dropout voltage of just 190mV (max. At full load) and a maximum quiescent current of 25µA at light load. An external enable pin allows the control logic to put the controller in standby mode, which reduces the current below 0.1 µA.
With a supply voltage rejection (SVRIN) of 90dB (1kHz, 20mA) and an output noise of just 8.8µVRMS (10Hz to 100kHz), the LD56020 provides a clean power bus for low voltage digital circuits. The circuit is stabilized with only one small ceramic capacitor at each of the input and output terminals. In addition to minimizing the number of materials, the low total number of components is combined with the controller’s small chipset (CSP) of 0.65 mm x 0.65 mm to provide a compact chain footprint with low impact on the size of the the printed circuit board.
The controller integrates protection functions, including short-circuit current folding and voltage blocking, to prevent excessive distraction in the event of a system failure. There is also protection against overheating and an internal discharge path.
200mA low-dropout voltage regulator operates with a supply from 1.1V to 5.5V
