LDO (Low Dropout) Linear Voltage Regulators, STMicroelectronics, Up to 100mA



LDO (Low Dropout) Linear Voltage Regulators, STMicroelectronics


The Low dropout or LDO is a linear voltage regulator. We have a wide range of linear regulators. The LDO regulator can operate with a small input–output differential voltage. LDO voltage regulators may offer fast transient response, wide input voltage range, low quiescent current and low noise with high PSRR.
