Frequently Asked Questions
What is the output voltage range of the TPS79501DCQ?
The TPS79501DCQ is an adjustable-output LDO. The output voltage is set by an external resistor divider connected to the FB pin. The output can be programmed from approximately 1.2V up to the input voltage minus the 200mV dropout, making it flexible for a wide range of supply rails in automotive and industrial designs.
What package does the TPS79501DCQ use and what are its dimensions?
The TPS79501DCQ comes in a 5-pin SOT-23-5 (DCQ) surface-mount package. This small-outline package is ideal for space-constrained PCB designs. The SOT-23-5 footprint is widely supported in standard PCB layout libraries, simplifying integration.
Is the TPS79501DCQ AEC-Q100 qualified for automotive use?
Yes. The TPS79501DCQ is AEC-Q100 qualified and rated for the full automotive temperature range of -40°C to +125°C. It is suitable for use in automotive infotainment, ADAS modules, body control units, and other under-hood or cabin electronics requiring reliable low-dropout regulation.
What are suitable alternatives to the TPS79501DCQ?
Compatible alternatives include the TPS79318DCQ (fixed 1.8V output, same package), MIC5205-ADJ (similar adjustable LDO in SOT-23), and the LP2985-ADJ (300mA adjustable LDO from TI). For higher current needs, TPS7A47 or LM1117ADJ offer higher output current with adjustable output.
What is the minimum input voltage for the TPS79501DCQ?
The TPS79501DCQ requires an input voltage at least 200mV above the desired output voltage due to its 200mV typical dropout. The absolute minimum input voltage is approximately 1.4V. For a 3.3V output, a minimum input of 3.5V is recommended to maintain regulation across temperature and load variations.
