A low quiescent current LDO is a low-dropout voltage regulator that has been designed to operate with a quiescent current (Iq, or self-consumption) that is significantly lower than or negligible in comparison to the typical load current it supplies.
Because it helps extend the battery life and reduces the overall power consumption, this feature is essential for power-budgeted applications, such as battery-powered devices or green-compliant equipment with extended standby operation.
For portable consumer devices like smartphones, smart watches, Bluetooth earphones, and wearables, low quiescent current LDO regulators are ideal.
In both operating and disabled (standby) modes, the extremely low quiescent current can also be beneficial to sensors for smart buildings, smart homes, and industrial applications. Smart meters, medical devices, and coin-cell powered devices are additional applications.
The Global Low Quiescent Current LDO Regulators market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Low quiescent current STMicroelectronics LDO Linear Regulators are designed to operate at a very low quiescent current (IQ). The average load current it supplies is greater than or equal to the IQ.
For power-constrained applications, such as battery-operated devices or environmentally friendly equipment with a prolonged standby operation, this capability is essential.
This increases battery life and lowers overall power usage. There are several possibilities for small footprint packages, including the SOT23-5L, SOT323-5L, Flip-Chip C4 from 0.65mm x 0.65mm, and DFN from 1mm x 1mm.
Five new very low and ultra low-dropout (LDO) linear voltage regulators have been introduced by ON Semiconductor, a leading provider of high performance silicon solutions for energy efficient electronics, to address a variety of automotive applications, including rear camera modules, instrument clusters, and body and chassis applications.
The newest criteria from automakers for very low quiescent currents when the ignition is switched off are met by these new devices, which provide 150 milliamperes (mA) of output current in integrated solutions that save space.
