Detailed Description for TLE42764DVATMA1
Product Overview
The TLE42764DVATMA1 from Infineon Technologies is a positive adjustable linear voltage regulator intended for regulated positive supply rails. It provides one adjustable output that can be set from 2.5V to 20V, accepts an input voltage up to 40V, and delivers up to 400mA. The device uses a surface-mount PG-TO252-5 package with a TO-252-5, DPAK (4 Leads + Tab), TO-252AD case. Its specified dropout is 0.5V at 250mA, quiescent current is 220 µA, and power-supply rejection is 54dB at 100Hz. An enable control is provided, along with over-current, over-temperature, reverse-polarity, and short-circuit protection. The part is specified for -40°C to 150°C and carries automotive grade and AEC-Q100 qualification.
Key Features
- Single positive adjustable output: 2.5V to 20V, maximum input voltage 40V, and output current 400mA.
- Dropout voltage: 0.5V at 250mA; quiescent current: 220 µA; PSRR: 54dB at 100Hz.
- Enable control for regulator activation or shutdown, supporting power sequencing and standby management.
- Protection features include over-current, over-temperature, reverse-polarity, and short-circuit conditions.
- Automotive grade and AEC-Q100 qualified; operating temperature -40°C to 150°C; surface-mount PG-TO252-5 package.
Applications
- Automotive electronic modules that need a locally regulated positive rail derived from a higher-voltage system supply.
- Embedded control boards using adjustable 2.5V to 20V rails for sensors, interfaces, or other low-current loads.
- Power subsystems requiring enable control and protection against over-current, over-temperature, reverse-polarity, or short-circuit events.
Design & Procurement Notes
When selecting TLE42764DVATMA1, confirm that the required output voltage is within 2.5V to 20V and that load current remains at or below 400mA. The input supply must not exceed 40V, and enough input-to-output differential should be retained to maintain regulation, particularly near the 0.5V dropout condition specified at 250mA. The 220 µA quiescent current should be included in standby power estimates, while the enable control can be used to activate or shut down the regulator. The surface-mount PG-TO252-5 package and the -40°C to 150°C operating range should be considered in board layout and thermal design. For systems requiring automotive qualification, review the AEC-Q100 grade and automotive classification against the target application requirements.
