The TL1963A-33DCQR from Texas Instruments is a robust and easy-to-use low-dropout (LDO) linear voltage regulator designed for various power management applications. It can handle an input voltage range from 2.4V to 20V and provides a stable fixed output voltage of 3.3V, with an adjustable output option available from 1.21V to 20V. The regulator is capable of delivering a maximum output current of up to 1.5A.
Key electrical characteristics include a typical dropout voltage of 340mV at 1.5A and low noise performance of 23µVRMS from 10Hz to 100kHz. Integrated fault protection features such as reverse-current, thermal shutdown, and overcurrent protection enhance system reliability. The device operates within a temperature range of -40°C to 125°C.
Packaged in a 6-pin SOT-223 (DCQ) surface-mount package, the TL1963A-33DCQR is suitable for designs requiring efficient power regulation in a compact form factor. It requires an output capacitor of at least 10µF with an ESR of less than or equal to 3Ω for stable operation.
