ADP151-EP is an ultralow noise, 200mA, CMOS linear regulator from Analog Devices. The product supports a wide temperature range of -55°C to +125°C, an input voltage range of 2.2V to 5.5V, and has a 9μVrms ultralow noise, 150mV dropout voltage, 265μA quiescent current and <1μA shutdown current.
The document describes the ADP151-EP Enhanced Product, a 5-lead TSOT package linear regulator designed for RF, VCO, and PLL power supplies in portable and battery-powered equipment. It features ultralow noise performance (9 µV rms) without requiring bypass capacitors on the input or output pins.
| Operating Supply Current (IGND) | 10 µA at 0 load, 265 μA at 200 mA load |
|---|---|
| Shutdown Current (IGND -SD) | < 1 µA |
| Input Voltage Range | 2.2 V to 5.5 V |
| Output Noise (10 Hz to 100 kHz) | 9 µV rms |
| Power Supply Rejection Ratio (PSRR) at 10 kHz | 70 dB |
| Dropout Voltage (VDROPOUT) | 150 mV at 200 mA load |
| Thermal Shutdown Threshold (TSSD) | 150 °C |
The device operates from -55°C to +125°C.
No, it achieves ultralow noise performance without the necessity of a bypass capacitor.
The regulator provides up to 200 mA of output current.
