The **ADP160ACBZ-3.0-R7** is a high-performance, ultra-low quiescent current, low dropout (LDO) linear regulator manufactured by Analog Devices. It is specifically designed for portable and battery-powered applications where power efficiency and space are critical. --- ## 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Output Voltage** | 3.0 V (Fixed) | | **Input Voltage Range** | 2.2 V to 5.5 V | | **Maximum Output Current** | 150 mA | | **Quiescent Current (No Load)** | 560 nA (Typical) | | **Dropout Voltage** | 60 mV @ 150 mA Load | | **Package Type** | 4-ball WLCSP (Wafer Level Chip Scale Package) | | **Accuracy** | ±1% Initial Accuracy | --- ## 2. Core Features & Functional Parts ### A. Ultra-Low Quiescent Current The standout feature of this IC is its **560 nA** ground current. This ensures that the regulator consumes almost no power itself, significantly extending battery life in "always-on" or standby modes. ### B. Low Dropout (LDO) Mechanism The device uses a specialized internal P-channel MOSFET pass element. This allows for a very low dropout voltage (60 mV), meaning the input voltage only needs to be slightly higher than the 3.0V output to maintain regulation. ### C. Protection Circuitry The IC includes several integrated safety features: * **Overcurrent Protection:** Prevents damage if the output is short-circuited. * **Thermal Overload Protection:** Shuts down the device if the junction temperature exceeds safe limits (approx. 150°C). * **Undervoltage Lockout (UVLO):** Ensures the device doesn't operate in an unstable state if the input voltage is too low. ### D. Enable (EN) Pin The "ACBZ" variant includes an active-high enable pin. When pulled low, the device enters a shutdown mode where it consumes less than 50 nA of current. --- ## 3. Typical Application Circuit The ADP160 is designed for stability with tiny ceramic capacitors, making the total solution footprint extremely small. ```text Input (2.2V-5.5V) ----[ C_IN 1uF ]----| VIN VOUT |----[ C_OUT 1uF ]---- Output (3.0V) | EN | | GND | ------------------ ``` --- ## 4.
