Microchip LDO Linear Voltage Regulators

LDO Linear Voltage Regulators

Choosing the right LDO linear voltage regulator is critically important. Power management is vital in a world driven by smaller devices reliant upon batteries that require efficient power consumption and precision. Microchip's linear low dropout LDO regulators feature ultra-low quiescent current, ultra-low dropout voltage, ultra-high ripple rejection, very accurate output, fast transient response, wide selection of packages and wide input voltage range.

Featured LDO Product
