The **ADP160ACBZ-2.3-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 wireless applications where battery life and space are critical. --- ### 1. Key Technical Specifications | Parameter | Value | | :--- | :--- | | **Output Voltage** | 2.3V (Fixed) | | **Input Voltage Range** | 2.2V to 5.5V | | **Maximum Output Current** | 150 mA | | **Quiescent Current (Iq)** | 560 nA (No Load) | | **Dropout Voltage** | 60 mV @ 150 mA | | **Package Type** | 4-ball WLCSP (Wafer Level Chip Scale Package) | | **Operating Temperature** | -40°C to +125°C | --- ### 2. Core Features * **Ultra-Low Quiescent Current:** Even under full load, the ground current remains exceptionally low, making it ideal for devices that remain in "sleep" or "standby" modes for long periods. * **Low Dropout (LDO):** The very low dropout voltage (60 mV) allows the regulator to maintain a stable output even when the battery voltage drops very close to the 2.3V target. * **Stability:** It is stable with tiny 1 μF ceramic input and output capacitors, reducing the overall PCB footprint. * **Protection Circuits:** * **Short-Circuit Protection:** Prevents damage during fault conditions. * **Thermal Overload Protection:** Shuts down the device if it exceeds safe temperature limits. --- ### 3. Pin Configuration (WLCSP) The device uses a 4-ball grid arrangement: | Ball | Symbol | Description | | :--- | :--- | :--- | | **A1** | **VIN** | Regulator Input Supply. | | **A2** | **VOUT** | Regulated Output Voltage. | | **B1** | **EN** | Enable Input. Drive high to turn on; drive low to shut down. | | **B2** | **GND** | Ground. | --- ### 4. Typical Application Circuit The simplicity of the ADP160 is one of its main advantages. A typical implementation requires only two external components: ```markdown VIN ----[ 1uF Cap ]---- (VIN) [ADP160] (VOUT) ----[ 1uF Cap ]---- VOUT (2.3V) (EN) (GND) | | Control Sig. GND ``` --- ### 5. Common Use Cases * **Mobile Phones:** Powering sub-circuits that require clean, steady DC. * **Wearables:** Smartwatches and fitness trackers where battery efficiency is paramount. * **IoT Sensors:** Remote sensors that must operate for years on a single coin-cell battery. * **Digital Cameras:** Powering low-voltage image processing components.
