TLE42642GHTMA1

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The TLE42642GHTMA1 is a positive fixed linear voltage regulator from the OPTIREG LINEAR series, manufactured by Infineon Technologies. It provides a nominal output voltage of 5 V with a maximum output current capability of 150 mA. The device operates within an input voltage range up to 45 V and features a typical dropout voltage of 220 mV at rated load. It maintains a low quiescent current of 70 µA and offers high power supply rejection ratio (PSRR) of 68 dB at 100 Hz. The component is housed in a PG-SOT223-4 surface-mount package and is qualified for automotive applications under AEC-Q100 standards.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated overcurrent protection, thermal shutdown, and short-circuit protection mechanisms ensure robust operation under fault conditions.
• High power supply rejection ratio effectively suppresses input noise and ripple to maintain stable output voltage.
• Automotive-grade qualification ensures reliability and performance consistency across wide temperature variations.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Applications

• Power supply conditioning for automotive electronic control units
• Voltage regulation for sensor interfaces in vehicle systems
• Backup power management for microcontroller units

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering suffix HTMA1 against official Infineon documentation to confirm compliance with RoHS directives and lead-free status. Confirm that the PG-SOT223-4 package matches your PCB footprint requirements. Ensure the selected variant meets the required AEC-Q100 automotive qualification level for your target application environment.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 5 V output is required with moderate current demands up to 150 mA. Consider its 45 V maximum input rating for systems with significant voltage fluctuations. Evaluate the 70 µA quiescent current for battery-sensitive designs. Verify that the thermal performance in the SOT223 package suits your heat dissipation constraints.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context
