Key Features
- Wide input voltage range from 4.15 V to 24 V absolute maximum enables operation from automotive, industrial, and unregulated power rails without additional protection circuitry
- Fixed 3.45 V output with only 0.415 V typical dropout voltage supports efficient regulation from a broad range of supply voltages
- Compact SOT-323 (5-pin) package provides a tiny PCB footprint suitable for space-constrained industrial and automotive sub-system designs
Applications
The TPS715345DCKRG4 is ideal for powering low-current microcontroller and sensor circuits in automotive body electronics, industrial instrumentation, and 12 V/24 V powered equipment where a wide-input-range LDO is required. Its high input voltage tolerance simplifies power supply design in systems where the input rail can swing from near battery voltage to load-dump transients. The device also suits always-on standby circuits, EEPROM supplies, and reference voltage rails in applications that benefit from a fixed 3.45 V supply derived from a high-voltage bus.

Frequently Asked Questions
What is the input voltage range of the TPS715345DCKRG4?
The TPS715345DCKRG4 accepts an input voltage from 4.15 V minimum up to 24 V maximum (absolute maximum also 24 V), making it suitable for automotive 12 V/24 V battery systems and industrial power rails without requiring additional series protection components.
What is the output voltage and maximum current of the TPS715345DCKRG4?
The device provides a fixed 3.45 V regulated output with a maximum output current of 50 mA, sufficient for powering microcontrollers, sensors, memory devices, and other low-power sub-circuits in automotive and industrial applications.
What is the dropout voltage of the TPS715345DCKRG4?
The TPS715345DCKRG4 has a typical dropout voltage of 0.415 V and a maximum dropout of 0.75 V at full load, enabling regulation to continue even when the input rail falls close to the output voltage level.
What package does the TPS715345DCKRG4 use?
The TPS715345DCKRG4 is packaged in the SOT-323 (5-pin) surface-mount package (JESD-30 code R-PDSO-G5), which has a smaller footprint than the standard SOT-23, helping minimize PCB area in compact automotive and industrial designs.
Is the TPS715345DCKRG4 suitable for automotive applications?
Yes, the TPS715345DCKRG4's input voltage range up to 24 V, combined with its compact package and robust design, makes it well-suited for automotive body control modules, infotainment ancillary supplies, and sensor interface boards where the device must tolerate wide battery and load transient voltage swings.
