The term **AS111PCP10/SPACE** refers to a high-reliability, space-grade linear voltage regulator, specifically the **AS111** series. These components are designed to provide a stable voltage supply in environments with extreme radiation and vacuum conditions. --- ### 1. Technical Specifications The AS111 series is typically a low-dropout (LDO) adjustable positive voltage regulator. Below are the general specifications for this class of component: | Feature | Specification | | :--- | :--- | | **Output Voltage Range** | 1.25V to 15V (Adjustable) | | **Output Current** | Up to 1.0 Amp | | **Dropout Voltage** | ~1.1V at full load | | **Input Voltage (Max)** | 20V | | **Package Type** | CP-10 (Ceramic Package, 10-lead) | ### 2. Key Characteristics * **Space Grade:** The "/SPACE" suffix indicates that the part has undergone rigorous screening and testing (such as MIL-PRF-38535) to ensure functionality in outer space. * **Radiation Hardened (Rad-Hard):** These parts are designed to withstand **Total Ionizing Dose (TID)** and **Single Event Effects (SEE)** caused by cosmic rays and solar particles. * **Thermal Stability:** The ceramic CP-10 package provides superior heat dissipation and hermetic sealing compared to standard plastic packages. ### 3. Pinout Configuration (Standard CP-10) In a typical 10-pin ceramic package for an LDO, the pins are generally assigned as follows: | Pin Number | Function | Description | | :--- | :--- | :--- | | 1, 2, 9, 10 | **V_OUT** | Regulated output voltage | | 3, 4 | **ADJ/GND** | Adjust pin for voltage setting | | 5, 6, 7, 8 | **V_IN** | Unregulated input voltage | ### 4. Application Logic The regulator maintains a constant output by comparing the internal reference voltage (usually 1.25V) against the feedback from the `ADJ` pin. In a space-constrained satellite environment, this part is used to power: * On-board computers (OBC) * Telemetry modules * Sensor arrays ---
