Detailed Description for TPS78601DCQR
Product Overview
The Texas Instruments TPS78601DCQR is a positive adjustable linear voltage regulator IC with a single output, rated for 1.5A. It uses a surface-mount SOT-223-6 package and supports input voltages up to 5.5V. The output can be adjusted from 1.2V to 5.5V, with a maximum dropout of 0.47V at 1.5A. The device includes an enable control and protection functions for over-current, over-temperature, reverse-polarity, and under-voltage lockout.
Key Features
- Positive adjustable output configuration with one regulator and an output range from 1.2V to 5.5V.
- Maximum input voltage of 5.5V and output current capability of 1.5A.
- Maximum voltage dropout specified as 0.47V at 1.5A.
- Quiescent current of 385 µA and power-supply rejection ratio of 59dB to 32dB from 100Hz to 100kHz.
- Enable control feature for regulator gating.
- Protection features include over-current, over-temperature, reverse-polarity, and under-voltage lockout.
- Surface-mount SOT-223-6 package with operating temperature range from -40°C to 125°C.
Applications
- Regulated positive rails for microcontrollers, sensors, and analog circuitry in embedded systems.
- Single-output linear regulation for portable instrumentation and data-acquisition hardware.
- Controlled power enable functions in board-level supply designs.
- Moderate-current load regulation in surface-mount power management assemblies.
Design & Procurement Notes
When selecting this regulator, confirm that the input voltage remains within the 5.5V maximum and that the desired output falls within the 1.2V to 5.5V adjustable range. Provide sufficient headroom for the 0.47V dropout specification at 1.5A, and account for linear-regulator power dissipation in the thermal design. Review the enable pin behavior and protection thresholds against the system requirements. The SOT-223-6 surface-mount package and -40°C to 125°C operating range should be compatible with the PCB assembly and environmental conditions.
