The ADP151AUJZ-1.2-R7 from Analog Devices is an ultralow noise, low dropout (LDO) linear regulator designed for high-performance applications. It provides up to 200 mA of output current with a fixed 1.2V output voltage, drawing from an input voltage range of 2.2V to 5.5V.
This regulator features ultralow noise of 9 µV rms without requiring a noise bypass capacitor, making it suitable for sensitive analog and RF circuits. It achieves stable operation with small 1 µF ceramic input and output capacitors. The device offers a low dropout voltage of 135 mV at a 200 mA load, improving efficiency.
Key electrical characteristics include a low quiescent current of 10 µA when idle and 265 µA at full load, along with a low shutdown current of less than 1 µA. The initial accuracy is ±1%, with accuracy over line, load, and temperature maintained within ±2.5%. It also provides 70 dB PSRR at 10 kHz and includes current-limit and thermal overload protection.
The ADP151AUJZ-1.2-R7 is available in a 5-lead TSOT package, suitable for surface mounting in space-constrained designs. It is AEC-Q100 qualified for automotive applications.
