## ADP160ACBZ-1.5-R7: Technical Overview The **ADP160ACBZ-1.5-R7** is a high-performance, ultra-low quiescent current, low dropout (LDO) linear regulator manufactured by **Analog Devices**. It is designed specifically for portable and battery-powered applications where power efficiency and space-saving are critical. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Input Voltage Range** | 2.2V to 5.5V | | **Output Voltage (Fixed)** | 1.5V | | **Maximum Output Current** | 150 mA | | **Dropout Voltage** | 60 mV @ 150 mA | | **Quiescent Current (No Load)** | 560 nA (Typical) | | **Shutdown Current** | < 50 nA | | **Package Type** | 4-ball WLCSP (Wafer Level Chip Scale Package) | --- ### 2. Functional Characteristics * **Ultra-Low Quiescent Current:** One of the standout features is its extremely low standby current. Even with a light load, it consumes very little power, significantly extending battery life in "always-on" circuits. * **Low Dropout (LDO):** The 60mV dropout means the input voltage only needs to be slightly higher than the 1.5V output to maintain regulation. * **Stability:** It is stable with small 1 μF ceramic input and output capacitors, which helps minimize the overall PCB footprint. * **Protection Features:** * **Overcurrent Protection:** Prevents damage during short circuits. * **Thermal Overload Protection:** Shuts down the device if the internal temperature exceeds safe limits. --- ### 3. Pin Configuration (WLCSP) Since this is a 4-ball WLCSP package, the layout is extremely compact (approx. 0.97 mm × 0.97 mm). | Ball | Symbol | Description | | :--- | :--- | :--- | | **A1** | **VIN** | Regulator Input Supply | | **A2** | **VOUT** | Regulated Output Voltage (1.5V) | | **B1** | **EN** | Enable Input. Drive high to turn on; drive low to turn off. | | **B2** | **GND** | Ground | --- ### 4. Application Areas * **Mobile Phones:** Powering sub-sections like sensors or digital logic. * **Wearables:** Smartwatches and fitness trackers requiring long battery life. * **IoT Devices:** Remote sensors that stay in sleep mode for long periods. * **Digital Cameras:** Portable imaging equipment. --- ### 5. Part Number Breakdown * **ADP160:** Series Name (Ultra-low quiescent current LDO). * **ACBZ:** Package Code (WLCSP). * **1.5:** Fixed Output Voltage (1.5V). * **R7:** Tape and Reel packaging (7-inch reel).
