The 12A29 is an integrated voltage regulator in a 4-pin package, designed for stabilizing output voltage in electronic devices with minimal external component requirements.

Key Features: 1. Regulator Type: Linear integrated voltage regulator. 2. Number of Pins: 4 (standard package, e.g., TO-92). 3. Input Voltage (VIN): Typically up to 30 V (exact range depends on the model). 4. Output Voltage (VOUT): Fixed (e.g., 5 V, 12 V, or other variants depending on the modification). 5. Maximum Output Current (IOUT): Up to 0.5 A (depending on the specific model). 6. Stabilization Factor: Ensures a stable output voltage with changes in input voltage and load. 7. Operating Temperature: From -40°C to +85°C (depends on the specific model).

Main Functions:

• Overload Protection: Limits output current to prevent damage. • Short-Circuit Protection: Automatically shuts off during a short circuit for safety. • Overheat Protection: Built-in thermal protection prevents the regulator from overheating. • Low Noise: Provides stable output voltage with minimal fluctuations or interference.

Features:

• Compact 4-pin package allows easy integration into PCBs. • Minimal external components required for proper regulator operation. • High reliability and stability under various load and temperature conditions.

Applications:

• Power supplies for low-power devices such as microcontrollers, sensors, and transducers. • Voltage stabilization in household, industrial, and automotive devices. • Use in compact devices and electronic systems where space-saving and voltage stability are critical.

The 12A29 regulator is a reliable and economical solution for stabilizing voltage in electronic circuits requiring a stable voltage level and ease of assembly.
