Analog DevicesADP121-AUJZ28R7Linear Regulators

The low 135 mV dropout voltage at 150 mA load improves efficiency and allows operation over a wide input voltage range. The low 30 μA of quiescent current at full load makes the ADP121 ideal for battery-operated portable equipment.

The ADP121 is available in output voltages ranging from 1.2 V to 3.3 V. The parts are optimized for stable operation with small 1 μF ceramic output capacitors. The ADP121 delivers good transient performance with minimal board area.

Short-circuit protection and thermal overload protection circuits prevent damage in adverse conditions. The ADP121 is available in a tiny 5-lead TSOT and 4-ball 0.4 mm pitch WLCSP packages and utilizes the smallest footprint solution to meet a variety of portable applications.

Never worry about components seeing unstable voltages again by implementing this LDO ADP121-AUJZ28R7 linear regulator manufactured by Analog Devices. Its typical dropout voltage at current is 0.09@150mA V. It has an overall accuracy of ±2 %. This voltage regulation device's single output can produce a current up to 0.15 A. Using the part will provide the power your application needs by requiring a voltage only of 2.3 V and not exceeding a voltage of 5.5 V. With a fixed output that has a voltage of 2.8 V, this is power management at its best. Operate at a constant current by utilizing the load regulation of 0.001%/mA(Typ) and line regulation of 0.03%/V. This product will be shipped in tape and reel packaging to allow for quick mounting and safe delivery. Its polarity is positive. This voltage regulation device has a minimum operating temperature of -40 °C and a maximum of 125 °C.
