High-PSRR Low-Noise RF LDO HL57XX Series

PublishTime：2025-03-21

The HL57XX series is a low-noise LDO (Low-Dropout Regulator) designed to supply up to 300 mA output current. It is tailored to meet the stringent requirements of RF and analog circuits, offering features such as low noise, high Power Supply Rejection Ratio (PSRR), low quiescent current, and low line or load transient response. The series utilizes innovative design techniques to achieve ultra-low noise performance without the need for a noise bypass capacitor. It also supports remote output capacitor placement, which enhances design flexibility. The HL57XX series is available in various package types and offers a wide input voltage range of 2.2 V to 5.5 V and an output voltage range of 1.0 V to 4.7 V. It is suitable for applications in mobile phones, tablets, digital cameras, audio devices, portable and battery-powered equipment, medical equipment, smart meters, field transmitters, RF, PLL, VCO, clock power supplies, IP cameras, and drones.
