The **ADP162ACBZ-1.8-R7** is a high-performance, ultra-low quiescent current, low dropout (LDO) linear regulator manufactured by Analog Devices. It is specifically designed for battery-powered portable devices where space and power efficiency are critical. --- ### 1. Key Technical Specifications | Parameter | Value | | :--- | :--- | | **Output Voltage** | 1.8V (Fixed) | | **Input Voltage Range** | 2.2V to 5.5V | | **Maximum Output Current** | 150 mA | | **Quiescent Current (Iq)** | 560 nA (No load) | | **Dropout Voltage** | 150 mV @ 150 mA | | **Package Type** | 4-ball WLCSP (Wafer Level Chip Scale Package) | | **Accuracy** | ±1% initial accuracy | --- ### 2. Core Features * **Ultra-Low Quiescent Current:** The most standout feature is its extremely low current consumption (under 1 µA), which significantly extends battery life in "always-on" or standby modes. * **Stability:** It is stable with small 1 µF ceramic input and output capacitors, minimizing the PCB footprint. * **Protection Circuits:** * **Short-Circuit Protection:** Prevents damage during fault conditions. * **Thermal Overload Protection:** Automatically shuts down if the internal temperature exceeds safe limits. * **Logic Controlled Enable:** Includes an EN pin to turn the regulator on or off electronically. --- ### 3. Pin Configuration (WLCSP) The device uses a tiny 4-ball grid layout: | Ball | Symbol | Description | | :--- | :--- | :--- | | **A1** | **VIN** | Regulator Input Supply. | | **A2** | **VOUT** | Regulated Output Voltage (1.8V). | | **B1** | **EN** | Enable Input. High = On, Low = Off. | | **B2** | **GND** | Ground. | --- ### 4. Common Applications Due to its small size and efficiency, it is typically used in: * **Mobile Phones:** Powering internal sensors or low-power logic rails. * **IoT Devices:** Wireless sensor nodes that spend most of their time in sleep mode. * **Wearables:** Smartwatches and fitness trackers. * **Digital Cameras:** Powering secondary logic circuits. --- ### 5. Part Number Breakdown * **ADP162:** Base model number. * **ACBZ:** Package code (WLCSP). * **1.8:** Fixed output voltage (1.8 Volts). * **R7:** Packaging suffix (indicates 7-inch reel/tape).
