LDO Full Form

LDO Full Form


An LDO (low-dropout) is a linear voltage regulator designed to operate with a very small input-to-output voltage difference (dropout voltage). The aim is to reduce the power dissipated as heat on the device and to increase the conversion efficiency. LDO systems offer great simplicity to design, as they are widely used in a wide range of applications due to the switching noise and small size. Diodes Incorporated has a comprehensive portfolio of LDOs that offer many different features like Ultra-Low IQ, High PSRR, Wide Input Voltage, Small Size and High Current.

Small-size LDOs: reduce form factor

Electronic designs are becoming denser and denser and as a result the PCB space is getting smaller and smaller. Diode's smaller size LDOs address this challenging task and provide the same high quality performance while consuming as little space as possible.

High PSRR LDOs: clean up the power supply

High PSRR LDOs easily power any system in rough power supply environments. They provide high rejection on power supply noise to provide clean DC power ensuring system reliability.

Low IQ LDOs: save power

Low IQ LDOs can help extend the battery life of a growing number of battery-powered devices. Conserving energy is a function of electronic equipment, and by reducing the quiescent current of LDOs, these products help to achieve low standby power in a variety of applications.

Wide input voltage LDOs: increase reliability and robustness

Diode's wide input voltage of up to 40 V LDOs provide simple, cost-effective solutions for supplying MCUs, embedded systems, sensors and other active components when facing high voltage environments. High accuracy and current limit functions make any design more reliable and robust.

High-current LDOs: heavy load, avoid switching noise

Switching noise can jeopardize performance in many applications. High-current LDOs of diodes up to 3A provide clean, accurate and efficient power for heavy, sensitive loads. Additional high-PSRR features eliminate LDO ripple, provide high output accuracy (up to 1%), and provide dropouts of 330 mV and below.
