Présentation
Description
Key specifications:
- Output current: Up to 1A
- Input voltage range: 2.5V to 15V
- Low quiescent current (~5mA)
- Built-in overcurrent and thermal protection
Common applications include powering microcontrollers, FPGAs, and low-voltage digital circuits. The CX suffix typically indicates a SOT-223 package, offering good thermal performance in a compact form.
Advantages:
- Simple to use (requires minimal external components)
- Stable with low-ESR capacitors
- Cost-effective for fixed-voltage needs
For precise details, always refer to the datasheet from the manufacturer (e.g., BL Microsystems).
Equivalent
- AMS1117-1.8
- LM1117-1.8
- AZ1117-1.8
- LT1117-1.8
These are fixed 1.8V output LDO regulators with similar specs (1A output, dropout voltage ~1.2V). Verify pin compatibility and electrical characteristics for your application.
Features
- Output Voltage: Fixed 1.8V
- Current Rating: Up to 800mA
- Low Dropout Voltage: Typically 1.1V at full load
- High Accuracy: ±1% output voltage tolerance
- Low Quiescent Current: ~5mA (typical)
- Protections: Overcurrent and thermal shutdown
- Package: SOT-223 (compact, surface-mount)
- Input Voltage Range: Up to 15V
Ideal for stable power supply in portable devices, embedded systems, and low-power applications.
Pinout
Pin Functions:
1. Input (VIN): Receives the input voltage (up to 15V).
2. Ground (GND): Reference for regulation.
3. Output (VOUT): Provides a stable 1.8V output (max current: 1A).
It features low dropout (~1.1V at 1A) and is commonly used for power regulation in circuits requiring a fixed 1.8V supply.
Application
1. Consumer Electronics – Powering microcontrollers, sensors, and displays in devices like smart home gadgets.
2. Industrial Systems – Providing stable voltage for PLCs, motor controllers, and instrumentation.
3. Automotive Electronics – Supporting infotainment systems and onboard modules.
4. Telecommunications – Regulating power in routers, modems, and networking equipment.
5. Embedded Systems – Ensuring reliable voltage for IoT devices and single-board computers.
Its 1.8V fixed output, low dropout, and compact SOT-223 package make it ideal for space-constrained, low-power applications.
