Texas Instruments Voltage Regulators - Linear Regulator Controllers UC2834Q

The UC2834Q is a linear regulator controller optimized for low input-output differential linear regulation. It supports both positive and negative voltage regulation designs, making it versatile for various applications. The device features a high gain amplifier capable of driving up to 200mA, facilitating high output current designs when paired with an external pass device. Key functionalities include an adjustable low threshold current sense amplifier for current limiting, and a fault monitoring circuit that detects under and over-voltage conditions. The fault alert system includes a programmable delay and a 100mA crowbar output for over-voltage protection, which can latch to maintain the output state during fault conditions. The UC2834Q also incorporates thermal shutdown protection to prevent excessive power dissipation. With an input supply voltage range of up to 40V and operational temperature ratings from -40¬8C to +85¬8C, this device is suitable for a wide range of environments and applications. The UC2834Q is packaged in a 20-PLCC format, making it compatible with various PCB designs.
