Detailed Description for TPS74801TDRCRQ1
Product Overview
TPS74801TDRCRQ1 from Texas Instruments is a positive adjustable-output linear regulator intended for regulated power rails. It provides one adjustable output from 0.8V to 3.6V at up to 1.5A, with a maximum dropout of 0.16V at 1.5A and an input voltage limit of 5.5V. The device includes enable, power good, and soft-start control features, along with over-current, over-temperature, short-circuit, and under-voltage lockout protection. It is specified for operation from -40°C to 105°C and is AEC-Q100 qualified for automotive-grade use, in a 10-VSON (3x3) surface-mount package.
Key Features
- Positive adjustable output with one regulator.
- Input voltage up to 5.5V and adjustable output from 0.8V to 3.6V.
- Output current rating of 1.5A.
- Maximum dropout of 0.16V at 1.5A.
- PSRR of 50dB at 1kHz to 30dB at 300kHz.
- Enable, power good, and soft-start control features.
- Over-current, over-temperature, short-circuit, and UVLO protection.
- Operating temperature range of -40°C to 105°C.
- AEC-Q100 qualified automotive-grade device.
- 10-VSON (3x3) exposed-pad surface-mount package.
Applications
- Regulated positive rails for microcontrollers, sensors, and digital logic in embedded boards.
- Power sequencing and status monitoring in systems requiring controlled startup and protection.
- Automotive-grade power management within the specified temperature range.
Design & Procurement Notes
Confirm that the input supply remains at or below 5.5V and that the target output lies within 0.8V to 3.6V. The 0.16V maximum dropout at 1.5A affects available headroom, especially when the regulator is used near its rated current. Enable, power good, and soft-start can support controlled startup and system status monitoring, while over-current, over-temperature, short-circuit, and UVLO protections address fault conditions. The 10-VSON (3x3) exposed-pad package requires suitable PCB pad and thermal layout for operation from -40°C to 105°C. AEC-Q100 qualification is relevant for automotive-grade selection, but system-level requirements should still be verified.
