## ADP3335ACPZ-5-R7: Technical Overview The **ADP3335ACPZ-5-R7** is a high-precision, low-dropout (LDO) linear regulator manufactured by Analog Devices. It belongs to the anyCAP® family, which is unique because it is stable with any type of output capacitor, regardless of the Equivalent Series Resistance (ESR). --- ### 1. Key Technical Specifications The following table summarizes the primary electrical characteristics of this specific variant: | Parameter | Specification | | :--- | :--- | | **Output Voltage (Fixed)** | 5.0 V | | **Output Current** | 500 mA | | **Input Voltage Range** | 2.6 V to 12 V | | **Dropout Voltage (Typ)** | 200 mV @ 500 mA | | **Accuracy Over Line/Load/Temp** | ±0.9% | | **Package Type** | LFCSP-8 (3mm x 3mm) | | **Operating Temperature** | -40°C to +85°C | --- ### 2. Core Features * **anyCAP® Technology:** This is the standout feature. Unlike many LDOs that require specific Tantalum or low-ESR Electrolytic capacitors for stability, the ADP3335 is stable with small Ceramic capacitors. * **Ultralow Quiescent Current:** In shutdown mode, it consumes less than 1 µA, making it ideal for battery-powered applications. * **Safety Protections:** * **Current Limit:** Protects the device during short-circuit conditions. * **Thermal Overload Protection:** Automatically shuts down the device if it exceeds safe operating temperatures. * **Error Flag:** Includes an active-low "Error" pin that signals when the output voltage falls out of regulation (e.g., during brownouts). --- ### 3. Pin Configuration (LFCSP-8) | Pin Number | Name | Description | | :--- | :--- | :--- | | 1, 2 | **OUT** | Regulated 5V Output. | | 3 | **ERR** | Error Flag (Open Collector output). | | 4 | **GND** | Ground reference. | | 5 | **NR** | Noise Reduction (Connect a capacitor to reduce output noise). | | 6 | **SD** | Shutdown input (Logic high to enable, low to disable). | | 7, 8 | **IN** | Unregulated Input Voltage. | | EP | **Exposed Pad** | Should be soldered to the PCB ground plane for thermal dissipation. | --- ### 4. Part Number Breakdown Understanding the nomenclature helps in identifying variants: * **ADP3335:** Base part number (500mA LDO). * **ACPZ:** Package indicator (LFCSP) and Lead-free/RoHS compliance. * **5:** Fixed output voltage (5.0V). * **R7:** 7-inch reel (indicates packaging format for automated assembly). --- ### 5. Application Circuit Example To utilize the device, minimal external components are required: ```markdown Input Voltage (5.5V - 12V) ----> [ IN ] [ OUT ] ----> 5.0V Output | | (Cin 1uF) = = (Cout 1uF Ceramic) | | [GND] [GND] ``` ---
