ADP151ACPZ-2.5-R7

ADP151ACPZ-2.5-R7 is an ultralow noise, low dropout (LDO) linear regulator. The low 135mV dropout voltage at 200mA load improves efficiency and allows operation over a wide input voltage range. Using an innovative circuit topology, the ADP151 achieves ultralow noise performance without the necessity of a bypass capacitor, making the device ideal for noise-sensitive analogue and RF applications. The ADP151 also achieves ultralow noise performance without compromising the power supply rejection ratio (PSRR) or transient line and load performance. The low 265μA of operating supply current at 200mA load makes the device suitable for battery-operated portable equipment. Applications include RF, voltage-controlled oscillator (VCO), and phase-locked loop (PLL) power supplies, mobile phones, digital cameras, and audio devices, portable and battery-powered equipment, post dc-to-dc regulation, portable medical devices, and automotive applications.
