Key Features
- 1 A output current with 450 mV typical dropout supports 2.7 V to 10 V input rails in automotive and industrial designs
- AEC-Q100 qualified for -40°C to 125°C operation ensuring reliability in underhood automotive power management applications
- Adjustable output voltage in 14-pin TSSOP package enables flexible post-regulation of multiple low-voltage digital supply rails
Applications
The TPS77601QPWPRG4CT is designed for automotive infotainment, ADAS sensors, and body-control modules that demand a reliable 1 A adjustable LDO regulator qualified to AEC-Q100 Grade 1 across the full -40°C to 125°C temperature range. Its 2.7 V to 10 V input range covers post-regulation from 5 V and 9 V automotive rails, while the 450 mV dropout ensures the output stays regulated even during cold-crank voltage drop events. The TSSOP-14 package is also well-suited for industrial motor controllers, telecom boards, and test equipment requiring a clean, adjustable DC rail from a switching pre-regulator.

Frequently Asked Questions
How much output current can TPS77601QPWPRG4CT deliver, and what is its dropout voltage at full load?
The TPS77601QPWPRG4CT delivers up to 1 A of continuous output current with a typical dropout voltage of 450 mV at full load. This means a 3.3 V output remains regulated as long as the input supply stays above approximately 3.75 V, making it suitable for systems that experience moderate supply sag during heavy loads.
Which automotive qualification does TPS77601QPWPRG4CT carry and what temperature range does it cover?
The device is AEC-Q100 qualified and rated for operation from -40°C to 125°C, satisfying the automotive Grade 1 requirement. This enables direct use in underhood ECUs, ADAS processing boards, and body-control modules where ambient temperatures can exceed 85°C during engine-bay operation.
How is the output voltage of TPS77601QPWPRG4CT set, and what range of output voltages is achievable?
The output voltage is set with an external resistor divider connected to the ADJ pin. The internal reference voltage and the resistor ratio determine the regulated output, allowing designers to set any voltage from the reference level up to approximately 9.5 V within the 2.7 V to 10 V input window, providing flexibility across multiple 1 A rail requirements.
In an automotive cold-crank scenario, how does TPS77601QPWPRG4CT maintain regulation when the 5 V rail drops?
During a cold-crank event, an automotive 5 V supply can dip to as low as 3.5 V for tens of milliseconds. With a 450 mV dropout, the TPS77601QPWPRG4CT can maintain a regulated 3.0 V or lower output rail throughout this dip, protecting MCUs and sensors that would otherwise lose power and reset during engine start.
